Patch: October 2016

The LIHC RPPA data submitted by MDACC were discovered to be mislabelled MESO samples. The analyses and standard data pipelines for LIHC have been re-run using the corrected samples submitted in March, and the nozzle reports now contain notices of the discrepancies.

 

The following table shows the changes in sample counts for RPPA data as a result of this patch:

HNSC

+145

(357 total)

LIHC

+121

(184 total)

THCA

    (7429 total)

  2. Significant changes to clinical data processing, to accommodate new XSD 2.7 format adopted by TCGA:
    1. Per TCGA this new format is not backwards compatible with the previous XML, so if you use a parser customized to the previous XSD, it may not work correctly.  This change is confined to the XML, no other TCGA data is affected by this change.
    2. These changes are detailed at https://wiki.nci.nih.gov/display/TCGA/Release+1.39.1#Release1.39.1-XSD2.7Implementation
    3. In the new format, 'CQCF' parameters are removed. Instead, they are provided in new XML format, SSF.
    4. According to this change, 'cqcf' parameters are removed and "patient.tumor_samples" and "patient.normal_controls" parameters are added in the clinical merged data. 
    5. Added parameters of two new XML formats, OMF and SSF in the clinical merged data 
  3. Fix a bug in Methylation_Preprocess that caused duplicate entries in methylation data
  4. Added outlinks to TCGA Encyclopedia to the About and Documentation menus of the Broad GDAC Firehose website
  5. FireBrowse v1.1.24:
    1. Loaded this data run
    2. Numerous internal updates to further simplify deployment, which e.g. will help provision AWG-specific databases
    3. The HeartBeat API function now includes: the directory from and time at which the API server was launched
    4. Dropped beta clause from version

Patch: November 2015

All mRNASeqV2 packages and derived packages have been updated for MESO and SKCM. Please ensure you are using the following 1.0 archives rather than the 0.0 ones for these cohorts: 

  • Merge_rnaseqv2__illuminahiseq_rnaseqv2__unc_edu__Level_3__RSEM_genes__data
  • Merge_rnaseqv2__illuminahiseq_rnaseqv2__unc_edu__Level_3__RSEM_genes_normalized__data
  • Merge_rnaseqv2__illuminahiseq_rnaseqv2__unc_edu__Level_3__RSEM_isoforms__data
  • Merge_rnaseqv2__illuminahiseq_rnaseqv2__unc_edu__Level_3__RSEM_isoforms_normalized__data
  • Merge_rnaseqv2__illuminahiseq_rnaseqv2__unc_edu__Level_3__exon_quantification__data
  • Merge_rnaseqv2__illuminahiseq_rnaseqv2__unc_edu__Level_3__junction_quantification__data
  • Methylation_Preprocess
  • mRNAseq_Preprocess

This is due to multiple versions of the same protocol in the SDRFs for these cohorts causing our data ingestor to drop samples. After conferring with the submitters, we've updated our tools to make an exception for this with RNASeqV2 data, and added the dropped samples back to the run.

  2. Extensive improvements to clinical data, in that Clinical_Pick_Tier1 archives now bundle 2 forms of values:

    1. Entire set of TCGA CDEs, verbatim (in new All_CDES.txt file): adding over 700 additional clinical parameters

    2. In addition to the CDE subset normalized by Firehose for downstream analyses (in <cohort>.clin.merged.picked.txt file)

    3. For example, to date the ACC picked file has contained less than 20 CDEs while All_CDEs.txt now contains more than 100.
    4. Followup values are merged, when available, to yield the most up-to-date values per CDE
    5. Corrected problem wherein some True/False values for regimen_indication CDE were erroneously swapped
    6. Created an interactive table CDEs, which on a single page shows exactly what CDEs are selected for analyses in Firehose for all disease cohorts. Updated the FireBrowse clinical samples API to reference this new CDE table
    7. Enhanced Merge_Clinical pipeline to leverage auxiliary CDEs when available (COAD, READ, ESCA): for all primary CDEs that also have a value in the aux CDE file (e.g. MSI), we now replace the primary value if it is NA and the aux value is not NA
  3. Extensive improvements to TCGA mutation data:
    1. New MAF for Diffuse Large B-cell Lymphoma (DLBC, 48 mutation samples)
    2. Oncotator now included in Firehose mutation pipelines, to standardize TCGA MAFs to a common format:
      1. This substantially improves the consistency and utility of TCGA MAFs
      2. hg18 MAFs lifted over to hg19
      3. All MAFs re-annotated against Gencode v19
      4. Oft-requested custom columns, such as amino acid change, now present in all MAFs
      5. Oncotated MAFs are available in 2 pipeline output archives
        1. Mutation_Packager_Oncotated_Calls
        2. Mutation_Packager_Oncotated_Raw_Calls
        reflecting the separation of MAFs into two sets (raw/automated and curated, per the Spring 2015 analysis run)
  4. Extensive improvements to RPPA data, fostering more robust automated processing and downstream analysis:
    1. Merge_protein_exp__mda_rppa_core__mdanderson_org__Level_3__protein_normalization__data
      1. Validation and animal source suffixes now stripped off of antibody name to account for several new batches that no longer include them
      2. Now returns a union of antibody names from all samples, rather than failing when all samples don't have the exact same antibodies
        1. This does not fix the below RPPA issues when different names for the same antibodies are used (e.g. Acetyl-a-Tubulin-Lys40/Acetyl-a-Tubulin(Lys40), ARHI/DIRAS3) - in these cases each antibody name will appear on separate lines of the merged files until a fix is made at MDACC.
        2. This enables RPPA analysis for aggregate cohorts such as STES, KIPAN, and GBMLGG
    2. RPPA_AnnotateWithGene: normalizes the antibody reference files provided by MDACC into a two-column tsv with standardized header, gene name, and antibody name (stripped of suffixes). This file is now provided in the archive.
  5. FireBrowse v1.1.17 beta:
    1. Ingest this August 2015 data run:
      1. API through which Firehose-picked and normalized clinical data are accessible has been renamed to Samples/Clinical_FH

      2. Verbatim TCGA clinical data may be accessed through the new Samples/Clincal API

      3. A CDE will be reflected in either API only when it has a value other than NA for at least 1 patient case in any disease cohort.

      4. For backward compatibility, the Samples/ClinicalTier1 remains available (as a synonym for Samples/Clinical_FH)
      5. fbget Python and UNIX CLI bindings have been suitably updated
      6. Which makes it extremely easy to determine for what patients and cohorts any given CDE is defined: e.g.
        fbget clinical cde=gleason_score
        will show each patient case with a valid gleason_score, across all cohorts
    2. viewGene: now enforces rendering of at most 1 gene per Submit; if multiple genes are given the first is selected
    3. iCoMut:
      1. Popup tooltips for mutation panels now show total # of mutations AND fractional % of a given type (e.g. missense)
      2. New search feature, enabling one to see into which clusters/panels/etc a given patient (or set of patients) falls
    4. After extensive testing, upgraded backend database from Mongo2.x to Mongo3.x: v3 dramatically reduces the memory footprint and data storage sizes, which yields greater performance and also clears considerable breathing room to add more data APIs (e.g. for methylation, RPPA, etc) as well as AWG-specific databases
  6. Corrected item # 9 from Spring 2015 data run: missing RPKM aliqouts in COAD 
  7. Issues: 
    1. RPPA issues due to changes in new data file row names: these have been previously reported to MDACC.
      1. KIRP: ARHI-M-E -> DIRAS3-M-E (batch 2.0.0)
      2. LGG: Acetyl-a-Tubulin-Lys40-R-C -> Acetyl-a-Tubulin(Lys40)-R-C (batch 2.0.0)
      3. PAAD: DIRAS3-M-E -> ARHI-M-E (batch 1.2.0)
      4. STES: ARHI-M-E -> DIRAS3-M-E (batch 2.0.0)
    2. RPPA issue with KIRC antibody file:
      1. Gene names were missing for 15 antibodies. The gene names were located in an online supplement file, and manually added:

        CA9

        CA9

        SDHB

    MAF+154(6738 total)
    miRSeq-2(10158 total)
    rawMAF+4250(4250 total)
    RPPA+696(6152 total)
  2. FireBrowseupdated to v1.1.11 beta to reflect ingestion of these data
    1. Python and UNIX fbget wrappers likewise updated to 0.1.4
  3. New / Updated MAFs:
    • SARC (247 samples)
    • Curated PRAD MAF: this MAF contains 332 samples, or 93 less than the rawMAF it replaced (and is why the total MAF count has not gone up by 247, but rather 247-93=154).
  4. rawMAFs: note that these were analyzed in 2015_04_02 analysis run, but heretofore not packaged within a stddata run
    • BLCA (395 samples)
    • COAD (367 samples)
    • COADREAD (489 sample)
    • GBMLGG (803 samples)
    • HNSC (508 samples)
    • KIPAN (678 samples)
    • KIRC (451 samples)
    • LGG (513 samples)
    • LUAD (542 samples)
    • OV (469 samples)
    • READ (122 samples)
    • SKCM (366 samples)
  5. To encapsulate these rawMAFs we've added 2 new Archive Types:
    1. Mutation_Packager_Raw_Calls: rawMAFs
    2. Mutation_Packager_Raw_Coverage: rawWIGs
  6. New RPPA:
    1. KICH (63 samples)
    2. MESO (63 samples)
    3. BLCA, LGG, KIRP, PAAD, and STAD also had new RPPA samples, but merging failed. See issues below.
  7. Updated clinical data stream (via the Clinical_Pick_Tier1 pipeline):
    1. SARC histological type now available
    2. Corrected issue where radiations.radiation.regimenindication was set to "no" if patient.radiations.radiation.regimenindication contained "adjuvant". It is now set to "yes" in such a case.
  8. 185 mRNASeq RSEM aliquots (TP=184,TM=1) added to ESCA cohort (esophageal), and ergo STES as well (aggregate STAD+ESCA cohort).
  9.  Issues: 
    1. COAD cohort missing RPKM aliquots: due to a preprocessor failure the RPKM mRNASeq aliquots for the following patients

      TCGA-AA-3841, TCGA-AA-3866,TCGA-AA-3870, TCGA-AA-3939, TCGA-AA-3941,

      TCGA-AA-3979, TCGA-AA-3980, TCGA-AA-3970,TCGA-AA-3977, TCGA-AA-3968

      are missing from our COAD stddata archives and FireBrowse. RSEM aliquots for these patients ARE available, however, and in general RSEM is preferred over RPKM for analysis. Finally, RPKM aliquots for these patients can be found in the aggregate COADREAD archives and FireBrowse database/api.

    2. RPPA failures due to changes in new data file row names: these have been reported to MDACC, but cannot be included in our stddata run until a comprehensive solution is available
      1. BLCA: no source/validation suffixes (batch 1.1.0)
      2. KIRP: ARHI-M-E -> DIRAS3-M-E (batch 2.0.0)
      3. LGG: Acetyl-a-Tubulin-Lys40-R-C -> Acetyl-a-Tubulin(Lys40)-R-C (batch 2.0.0)
      4. PAAD: ARHI-M-E -> DIRAS3-M-E (batch 2.0.0)
      5. PRAD: ADAR1-R-V -> ADAR1-M-V (batch 2.0.0)
      6. STAD: ADAR1-R-V -> ADAR1-M-V (batch 2.0.0)

  1. Summary of sample changes (see the comprehensive samples report for more details):

    Clinical+252(10945 total)
    MAF+125(6584 total)
    miRSeq+1(10160 total)
    RPPA+188(5456 total)
  2. New/Updated MAFs:
    • CHOL (35 Samples)
    • PAAD (+23 Samples)
    • STAD (+68 Samples)
    • TGCT (-1 Sample)
  3. Added new aggregate cohort STES, combining Stomach adenocarcinoma (STAD) and Esophageal carcinoma (ESCA) into a 628-patient cohort
  4. Updates to FireBrowse portal:
    1. Loaded with this stddata__2015_04_02 run
    2. Rationalized "requiredness" to be consistent across entire API: 
      1. Now, nearly all functions require that at least one gene OR cohort OR barcode be specified
      2. This increases query performance, and clarifies API semantics
    3. New Quartiles API for mRNASeq expression, providing a summary of expression across all samples in a disease cohort, suitable e.g. for boxplot visualization
    4. Corrected docs for SampleTypeBarcode function to indicate that it takes only 1 barcode (as a "path parameter")
    5. Changes to the default sort parameter for several API functions:
      1. mRNASeq api and miRSeq functions now default to disease cohort instead of gene and mir, respectively
      2. significantly mutated genes and mutation file functions now default to disease cohort instead of Q value and gene, respectively
    6. When iterating over multiple pages of TSV, CSV output, the api will now return a header for ONLY the first page
    7. Columns containing commas are now delimited with double quotes in CSV return payloads
    8. Increased tolerance for messy input: distinct values of multi-valued parameters (e.g. gene=egfr,tp53,BRCA1 in mRNASeq samples api) may now be delimited by arbitrary whitespace (in addition to commas, as previously supported)
    9. In the interactive docs UI the page and page_size parameters are no longer required by any API function: they continue to default to reasonable values for the common case.
    10. The payload of the SampleTypes api now returns the description of the sample type (e.g. TP = tumor primary)
    11. An empty response is now returned when no records in FireBrowse match a given query; previously a payload such as

       

      {
      "mRNASeq": []
      }

      would be returned in such cases (e.g. for this mRNASeq query).

    12. removed spurous tcga_aliquot_barcode column from payload of miRSeq samples function (was visible in TSV and CSV return formats)
    13. avoid MongoDB conflict (and exception thrown) with certain MetaData/Counts api calls (reported by M. Deng)
  5. ISSUES: In the prostate (PRAD) RPPA data, the antibody source for ADAR1 changed from Rat to Mouse (ADAR1-R-V → ADAR1-M-V) between 1.0.0 and 2.0.0; this broke the Firehose sample merge pipelines, which requires all row names for each sample to match in order to generate a consistent table samples table.

  • FireBrowseupdates:
    • Loaded this 2015_02_04 data run
    • Expose the Link header within the response header payload of each API request, for CORS-enabled pagination within Javascript codes.

    • By default only RSEM expression values will be returned now for mRNASeq api calls, instead of a mix of RSEM and RPKM values (which could be confusing). RPKM expression values can still be obtained by including a &protocol=RPKM parameter.

      Note that due to the use of different antibodies for GBM & LGG we are unable to merge the RPPA data into a single table for this cohort
    • FPPP : FFPE Pilot Phase II
  • FireBrowse:
  • Run scheduling: given slowdown of data flow in TCGA, coupled with staff reductions, we are again adjusting our run schedule:
    1. Standard data runs will now be initiated bi-monthly (~8 weeks apart) instead of every 6 weeks
    2. Standard analysis runs will still be performed for every other data run, but that will result in 3 a year now instead of 4
    3. Custom AWG runs will still be performed on an as-needed basis

  • mRNASeq data:
    • Z-score now computed for RSEM/RPKM mRNAseq, calculated as
      z = (expression in tumor sample - mean expression in all tumor samples) / standard deviation of expression in all tumor samples
  • mirSeq data:  
    • miRseq_Mature_Preprocess pipeline updated to miRbase v21, will now generate same mature miR calls as BCGSC
  • Clinical data updates: 
    • corrected value of dccuploaddate CDE to be an actual date value instead of text showing how the date would be computed
    • normalized CDEs to contain underscores for readability: e.g. dccuploaddate became dcc_upload_date, etc
      • this is evident in Merge_Clinical and Clinical_Pick_Tier1 pipelines
      • as well as in the results returned by the FireBrowse clinical samples API
    • 2 formerly PHI clinical data elements, race and ethnicity are now available in Clinical_Pick_Tier1 pipeline output
  • FireBrowse Updates:
    • Samples/mRNASeq API: 
      • new Z-scores (see above) added to results
      • geneID now reflected in results, because in some cases the gene name is absent
    • Samples/clinical samples API:
      • tier1_cde_name parameter added, to allow pinpoint retrieval of specific CDEs
      • date parameter removed, for consistency with other Samples APIs (only latest available data is served)
      • Added Implementation Notes documentation at top of clinical API section
    • New Metatdata/ClinicalTier1 API: lists names of all tier 1 clinical data elements (CDEs), unioned over all disease cohorts
    • New comprehensive file download dialogue, per disease cohort: 
      • See for example this example for adrenocortical carcinoma (ACC)
      • This enables one to see all files for any disease cohort, in a single view
      • And will be enhanced in the near future to have checkboxes to include/exclude files for aggregate download
      • Also linked to the data column for each disease cohort on main GDAC site

    • Previously only mRNAseq_Preprocess was executed during our stddata workflow
    • And all other preprocessors were executed as preliminary tasks in our Analysis workflow
    • The following modules have therefore been migrated from the analysis workflow to stddata workflow:
      • Methylation_Preprocess
      • mRNA_Preprocess_Median
      • miRseq_Preprocess
      • miRseq_Mature_Preprocess
    • In addition, the code for the folllowing preprocessors has been updated:
      • miRseq_Mature_Preprocess:
        • corrected the output file name from "PKM" to "RPM"
        • An additional output file created, of matrix without log2 transform
      • mRNAseq_Preprocess: addtional output file created, of matrix without log2 transform
  • Merge_Clinical module updated: output will now include biospecimen information (BCR), when available

  • Clinical data for Adrenocortical Carcinoma (ACC) have been restored. See 2014_02_13 redaction notice below for more details.
Patch: Data Redaction Performed February 13, 2014

Due to a PHI breach at one of our upstream data sources, where protected health information was accidentally included in the clinical data files for the Adrenocortical Carcinoma disease study (ACC), we have deleted all of the ACC stddata archives for the following tasks

  • Clinical_Pick_Tier1
  • Merge_Clinical
from the December 2013 and January 2014 stddata runs (2013_12_10 and 2014_01_15, respectively). These clinical data archives will re-appear in the forthcoming February 2014 stddata run. No downstream Firehose analyses were impacted by this PHI breach.

  • Samples Report now loads much faster: bulky sections (Filtered Samples, FFPE Cases, and Additional Annotations) converted to links
  • mRNASeq Preprocessor updated to merge Illumina GA2 and Illumina HiSeq data if both are available in similar formats (either RPKM or RSEM)
    • Our previous approach (of not merging) was unnecessarily conservative, because samples are typically NOT sequenced on both platforms
    • For example: patients A, B sequenced only on Illumina GA2, and patients Y, Z sequenced only on Illumina HiSeq
    • Previously, Illumina HiSeq data was used exclusively in downstream analyses when available (RSEM preferred over RPKM).
    • This merge should be evident as significantly higher sample counts in downstream mRNASeq analyses (and reports)
  • New / Updated MAFS:
    • LGG
    • UCS
    • BRCA
  • New MESO disease type (mesothelioma)

  • Please note that we've introduced a new procedure for handling FFPE aliquots in our stddata processing: even though it has been shown that with sufficient care it is possible to perform TCGA-like cancer genome analyses on FFPE samples, confounding batch effects may be introduced if FFPE aliquots are combined with frozen tissue aliquots in the same analysis. To avoid these and maintain the highest quality downstream analyses, as of this September 2013 run we are segregating FFPE samples from frozen tissue samples; this is reflected as a small decrease in the sample counts of our uploaded stddata archives. If you wish to perform analyses on FFPE-only sample sets, they will appear in the October 2013 stddata run as distinctly-named <Disease_Cohort>-FFPE archives.

  • Clarified how followup data are systematized during our clinical data processing: that is, for each patient we
    1. Check vital status
      For each patient,
      1. vistal status
        1. if any version of vital status parameter value is 'deceased' then fill the picker vital status parameter value with 'deceased'
        2. if not, fill the picker vital status parameter value with 'living'
        => in selectionFileGenerator.R in picker module
        followup.vitalstatus <- paste("=ifelse(",paste(rownames(patientData)[w.vitalstatus], "==\"deceased\"",collapse=" | ") ,",1, 0)")

      2. days to last followup
        1. First check vital status, 
        if the patient's vital status parameter value is 'deceased', then fill the 'days to last followup' parameter value with 'NA'. 
        2. if the patient's vital status parameter value is 'living' then, go to parameter 'days to last followup' and check all versions of'days to last follow up' parameters and pick up the maximum number of the parameter values.

        => in selectionFileGenerator.R in picker module
        followup.daystolastfollowup <- paste("ifelse(", any.deceased, ",\"NA\",", max.any.daystolastfollowup,")", sep="")
      3. days to death
        1. if the values of all version of days to death parameter is NA then fill the days to death parameter value with NA
        2. if not, fill the days to death parameter value with the maximum number of the parameter values among any version of days to death parameters values
        => in selectionFileGenerator.R in picker module
        followup.daystodeath <- paste("ifelse(", all.na,",\"NA\", max(", any.daystodeath, ",na.rm=T))", sep="")

  • IMPORTANT: this will be the final installment of our bi-monthly cycle of Firehose stddata package releases. In order to better focus on serving AWG needs, evolving computational methods, and the portals used to disseminate & explore them, we are switching to a monthly release cycle. Our next Firehose stddata run will be cut from data snapshot in mid July 2013, and released shortly thereafter.

  • The Samples Summary Report for each run now reflects significantly higher-resolution metadata per disease cohort:
    • In addition to the combined list of all excluded samples (across all diseases) the report now also lists those per disease cohort
    • Consider e.g. the LUAD example below: 1 sample was redacted, 126 were filtered as replicates, and 6 were blacklisted
    • Data resolution down to the aliquot is now reflected in the report, for samples both included and excluded
    • The sequencing platform, submitting center, data level, and protocol are also reflected
    • As well as the sample type (e.g. primary tumor, recurrent tumor, normal blood, etc.) for each ingested aliquot
  • We believe this level of clarity, comprehensiveness, and ease of access raises the bar for data resolution in TCGA
  • Blacklisted 138 STAD copy number samples (from batch 220, determined by A. Cherniack to have wrong sample names)

      • 5 parameters for tumor aggressiveness (distant.metastasis, extrathyroidal.extension, lymph.node.metastasis, completeness.of.resection, number.of.lymph.nodes)
      • 4 parameters for tumor staging systems for THCA (tumor.stagecode, neoplasm.diseasestage, multifocality, tumor.size)
        • tumor.size = max(dimension.depth, dimension.length, dimension.width)
    • MAFs updated to sync with DCC:
      • BLCA v1.3
      • BRCA v5.2 (+265 Tumor Samples)
      • CESC v1.4 (+3 Tumor Samples)
      • LAML v2.12 (-2 Tumor Samples)
      • LUSC v1.5
      • PRAD v1.3
      • UCEC v1.4
    • hg19 WIGs added:
      • BRCA
      • UCEC
      • GBM
    • Addressed UUID uppercase bug in our dicer which accidently removed 63 COAD RPPA samples; fix will be evident in data stream after SDRF is updated at DCC.
    • Added Firehose AWG Runs page to the NCI Wiki, as a central reference point for custom runs done on behalf of active AWGs. This effort has several aims:
    • Currency: Firehose can be run on the latest daily snapshot of data from the DCC, avoiding the time & sample lag of monthly runs
    • Flexibility:  additional runs can be easily performed on AWG-curated disease subtypes, and even include custom analyses
    • Speed:  custom AWG runs can be executed in only a few days time (excluding computationally intensive algorithms that may take >1 week to run)
    • Familiarity:  using the same internal Firehose machinery, and external-facing dashboards, Nozzle reports etc, already known to the community
    • Scope: stepping stone to open-access Firehose, that can be manipulated directly by TCGA researchers instead of having runs curated only at the Broad

  • LGG MAF corrected (see 2012_12_21 errata below)
  • Given our desire to support TCGA AWGs more extensively in 2013, and that AWG runs are timed more to telecon & workshop schedules, this will be our only stddata run in January 2013.  The next stddata run will be initiated in the first week of Feb, after our first complete Feb download from the DCC.

  • In a joint decision with the PANCAN awg, we will discontinue generating the PANCAN18 cohort until at least May 1 2013.  For this run we have uploaded PANCAN18 to the DCC, but it will not be retrievable with firehose_get.

  • We have initiated the export to IGV of this run, and expect it to be completed by 10pm EST tonight and available to the public Sat Jan 26.  Until then, your IGV menus will not show the 2013_01_16 run.

Errata for 2012_12_21 (issued 2013_01_22)

Due to a dicing issue, the PAAD MAF was processed rather than the LGG one for the 12/21 run.  The correct file had been swapped in prior to the run, but the dicer did not recognize the swap, and didn't process the LGG MAF.  Our next run will have the correct LGG MAF. This affects mutation results for LGG in the analyses__2012_12_21 run as well.

      • please note that, per the AWG, this MAF contains contaminated samples; a new MAF is currently under construction by the AWG, and should be ready for inclusion in our next stddata run.

  • Removed old v1.3 KIRC MAF (current version is 1.4)
    • This accounts for the 110 sample drop for KIRC MAF tumor samples
    • We are aware of a new v1.5 of the KIRC MAF posted to a non-standard location rather than the DCC. If appropriate, it will be added to our next stddata run, replacing v1.4 and bringing the KIRC MAF tumor sample count to 499.

Errata for 2012_10_24 (issued 2012_11_19)

 

Our internal rewiring to accommodate normal samples induced a hiccup which required several MAF packager files to be reissued for the stddata__2012_10_24 run.  The new files have been uploaded to the DCC and will be available in the protected data tree pending internal mirroring by the DCC, or may be downloaded presently via firehose_get.  The newly issued files are identifiable as

  • No significant sample changes 26 Aug - 06 Sept (see Spreadsheet).
  • To assist the melanoma AWG we delayed the first stddata run of Sept 2012 to incorporate pending submission of RPPA samples for SKCM, which appeared in our mirror as of 9/13.  As this was essentially the midpoint of September stddata__2012_09_13 WAS THE ONLY STDDATA RUN for SEPT 2012.  This simplified our work somewhat, without appreciably reducing the sample flow, while also allowing us to re-sync to our desired target stddata run schedule of the 1st and 15th of each month.

  • COAD and READ reintroduced as separate types by request of the PANCAN8 AWG (COADREAD aggregate continues to be available)

2012_08_25 Correction (issued 2012_09_17)

The LUAD mafs we ingested in stddata__2012_08_25 had non-standard headers. We've since enhanced our MAF ingestor to correct such headers when detected, and re-released the LUAD maf yesterday (17 Sept. 2012). New tarballs are available from firehose_get, and soon the DCC, as:

  • gdac.broadinstitute.org_LUAD.Mutation_Packager_Calls.*.2012082500.1.0.tar.gz

    The -1's in this table were caused by the removal of several samples for two OV patients, due to an unintended clash between improved aliquot selection (as described in our FAQ) and a legacy internal blacklist from the TCGA pilot. The legacy blacklist has now been deprecated, in favor of relying solely on the transparency of redactions recorded in the DCC annotations database, and the samples will be present in future releases. The OV samples in question are:

    • TCGA-29-1704
      • CN
    • TCGA-23-1023
      • mRNA
      • miR
      • Methylation

2012_06_06
  • 526 new miRseq samples and 153 new clinical samples
  • Mutation_Packager_Coverage task:
    • Use soft links instead of packing multiple copies of identical coverage files, for dramatic disk savings: e.g. reduced archive size from 58Mb to 2 Mb for 28 BLCA samples, from 697Mb to 3 Mb for 248 UCEC samples, etc!
    • Valid SDRF now included in DCC archive 
  • Mutation_Packager_Calls task now includes valid SDRF in DCC archive
  • Merge_Clinical task now includes valid SDRF in DCC archive  
     

May 2012
  • New RPPA_AnnotateWithGene pipeline, which:
    • Maps antibody proteins to gene symbols, to simplify downstream analyses.  The gene symbols come from the MDA_RPPA_Core.antibody_annotation.txt file packaged in the mage-tab archive of each RPPA submission.
    • Includes a figure showing the protein expression levels per sample.
  • Mutation_Packager: split into two files, Mutation_Packager_Calls and Mutation_Packager_Coverage, for smaller downloads if all one wants are MAFs.
  • Prostate (PRAD) mutation data now present (83 samples)
  • Per Program Office, all clinical and mutation data are now public, so we no longer cull them prior to hosting on Broad GDAC site.
  • New Broad GCC SNP6 data format, in which all samples from the single platform

         Merge_snp__genome_wide_snp_6__broad_mit_edu__Level_3__segmented_cna__seg

    have been reprocessed in 4 distinct ways (each containing the full complement of samples):

April 25, 2012
  • Phase 2 SDRFs implementation: all Merge_<platform> pipelines now have SDRFs (clinical and MAF packages will be added next run)

  • Redactions report now included on stddata dashboard
  • Corrected 2 clinical issues: reducing to 5 the # patients with days_to_death=0, and ensuring vitalstatus=living implies days_to_death=NA
  • Reduced copy number sample count by 824, to correct  erroneous counting of tangent-normalized SNP6 data (will be in next run)


April 12, 2012
  • 128 new methylation samples, including fix for missing 450 platform Beta values
  • 824 new copy number samples
  • Initial bundling of RPPA data type, with 2087 samples packaged for proteomics QC review
  • Phase 1 of companion SDRFs implementation: phase 2 in next data run will complete implementation.

March 21, 2012
  • Almost 800 new methylation samples:  Human Methylation 450 platform included for first time
  • MAFs for stomach (STAD, 133 samples) and cervical (CESC, 36 samples) included for first time
  • New firehose_get utility, for simpler downloads.

March 6, 2012
  • Draft PANCANCER dataset included:  34 of 40 possible pipelines ran to completion, for an 85% success rate.  At present this represents a simple aggregation of all tumor data, e.g. irrespective of hg18 versus hg19 alignment, but we will be advocating in followup TCGA discussions that these and other distinctions (like platform) will need to be considered more carefully in order to maximize scientific accuracy.
  • 1100 more methylation samples

  • First samples of bladder cancer (BLCA) mutation data: 28 in all

  • To simplify access, all public archives from our stddata runs are now also hosted directly from Broad servers; no Level_1, Level_2, or Clinical PHI data is included, and credentialed download from the DCC remains the only way these protected data may be obtained.

February 2012
  • Due to low sample differentials in early Feb we performed only 1 stddata run this month.
  • Methylation sample count increased by more than 1000 to 3290.

  • mRNAseq sample count increased by more than 300 to 2070.

  • Approximately 300 new BCR and clinical data samples.

  • With clinical data elements remaining stable since Sept 2011 for many tumor types, we've resumed execution of our Tier1 CDEs picker pipeline, with this including CDEs for 14 tumor types (versus only 8 tumor types when Tier1 CDEs were last packaged in summer of 2011)

January 2012

  • Absolute counts for Jan 2012 data runs have changed very little from December 2011.

  • As of 2012_01_24 run we believe redactions & rescissions are accurate to ~100% of DCC annotations database (with thanks to M. Ferguson for assistance).  Please report to gdac@broadinstitute.org if you find otherwise.


December 2011
  • To simplify data retrieval, the Tumor Type cells in our dashboard now link directly to the DCC locations from which the corresponding archives may be downloaded.
  • All MAF and WIG files that are available to and processed by the Broad GDAC are now bundled within our stddata package.
  • In the 2011_12_30 data run the LUAD MAF count dropped to 148, as we corrected an error that resulted in the elimination of 110 spurious LUAD mutation samples.

November 2011
  • Due to ongoing software development and manual data collection efforts, no RNA-Seq or MAF data was included in the Nov 15, 2011 stddata runs. 

  • RNA-Seq data were bundled in the Nov 28 stddata run, and both RNA-Seq and MAF data will be bundled with the December 2011 runs.

  • Clinical data have been bundled as of Nov 28 as well.
