Release 2.3.1

• GDC Product: GDC Data Portal
• Release Date: November 21, 2024

New Features and Changes

• Custom filter cards in the Cohort Builder will be automatically removed if the property is no longer available.
• File names for manifests now include the timestamp. Additionally, dates and times are now based on the user's timezone rather than UTC.
• Responsiveness improvements have been made to the Cart.
• Minor UX improvements.

Bugs Fixed Since Last Release

• Adding family_histories.relationship_age_at_diagnosis or follow_ups.other_clinical_attributes.undescended_testis_corrected_age_range as a custom filter in the Cohort Builder will no longer result in endless spinners being displayed on these filter cards.
• Fixed an issue where the Replace Existing Cohort modal is not being displayed when creating a cohort from Mutation Frequency.
• Minor UI and font fixes.

Known Issues and Workarounds

• Section 508 Accessibility:
  • There are known Section 508 accessibility issues that the GDC plans to address in subsequent releases. If a user encounters a Section 508 barrier, please contact GDC Support (support@nci-gdc.datacommons.io) for assistance. Known Section 508 issues are identified below.
    • There are keyboard focus and navigation issues in analysis tools that use popup windows/overlays for custom user selections. Impacted analysis tools include BAM Slicing, Sequence Reads, Gene Expression Clustering, OncoMatrix, and ProteinPaint.
    • Heatmaps within the Sequence Reads tool do not contain concise alternative text or equivalent alternatives.
    • In the Gene Expression Clustering tool and OncoMatrix, there are no headers for genes, clusters, and/or cases in the heatmap.
    • In the Gene Expression Clustering tool, color is used to convey gene expression values but there are no patterns to convey the same information as color. Color is also used in ProteinPaint and the Sequence Reads tool to convey consequence type but there are no distinguishing patterns.
    • Some text can be difficult to read on a small screen at a 200% zoom level.
• Survival Plot:
  • In Mutation Frequency, the downloaded image may display a survival curve when none is plotted within the portal.
  • When the survival plot is zoomed in and an image is downloaded, the curves within the image may extend beyond the y-axis.
• Gene Expression Clustering:
  • The tool allows deleting the gene expression group and displays an uninformative error message after submitting the deletion.
• In ProteinPaint, the "Gene Expression" option is non-functional when filtering samples in a sub-track.
• Using multiple browser tabs with the portal when adding or removing files from the Cart may result in the Cart not being updated as expected.
• In the files, cases, and annotations tables, the case ID search field is case-sensitive. If the search does not return the expected results, try changing the input to uppercase as case IDs are most commonly uppercased.
• Cohorts filtered by mutated genes and SSMs not in those genes will result in 0 cases since the mutations have to belong to those particular genes in order to match cases for the results. As a workaround, first filter the cohort by the mutated genes and export the cohort using the Export Cohort feature in the Cohort Bar. Then, reimport the cohort using the Import New Cohort feature before applying the SSM filters.
• The Slide Image Viewer will display a black image temporarily if a user zooms in on a slide then switches to another slide.
• The TSV of the Most Frequent Somatic Mutations table in the case summary page does not reflect the displayed information in the table if a search filter has been applied.
• Repeated and consecutive uses of the browser's back and/or forward buttons to return to a previously viewed page may result in a different page being displayed than the one indicated in the browser address bar.

Known Issues and Workarounds

• Section 508 Accessibility:
  • There are known Section 508 accessibility issues that the GDC plans to address in subsequent releases. If a user encounters a Section 508 barrier, please contact GDC Support (support@nci-gdc.datacommons.io) for assistance. Known Section 508 issues are identified below.
    • There are keyboard focus and navigation issues in analysis tools that use popup windows/overlays for custom user selections. Impacted analysis tools include BAM Slicing, Sequence Reads, Gene Expression Clustering, OncoMatrix, and ProteinPaint.
    • Heatmaps within the Sequence Reads tool do not contain concise alternative text or equivalent alternatives. Additionally, equivalent alternatives to the Box plots, QQ plots, Venn diagrams, and the body plot on the home page are not available.
    • In the Gene Expression Clustering tool and OncoMatrix, there are no headers for genes, clusters, and/or cases in the heatmap.
    • In the Gene Expression Clustering tool, color is used to convey gene expression values but there are no patterns to convey the same information as color. Color is also used in ProteinPaint and the Sequence Reads tool to convey consequence type but there are no distinguishing patterns.
    • Some text can be difficult to read on a small screen at a 200% zoom level.
• Cohorts:
  • Cohorts are under active development and their behavior may change in the first several months after the release of GDC Portal 2.0. As this process may result in the loss of saved cohorts on the portal, we highly recommend exporting cohorts locally.
  • Cohorts created based on CNV losses or gains may not have the correct composition when filtered by additional mutated genes. As a workaround, first filter by the mutated genes before creating cohorts based on CNV losses and gains.
  • Cohorts filtered by mutated genes and SSMs not in those genes may unexpectedly result in 0 cases.
  • Cohorts containing FM-AD cases may not update correctly when users with dbGaP access to FM-AD (phs001179) log in or out. As a workaround, logging in before creating cohorts with FM-AD cases is recommended.
• Survival Plot:
  • The survival plot in Cohort Comparison does not display text indicating that there is insufficient survival data to plot.
  • In Mutation Frequency, the downloaded image may display a survival curve when none is plotted within the portal.
  • When the survival plot is zoomed in and an image is downloaded, the curves within the image may extend beyond the y-axis.
• Cart:
  • Spinners on the Download Cart and Download Associated Data buttons may be displayed longer than expected. This is a visual issue and does not affect the use of these buttons.
  • Using multiple browser tabs with the portal when adding or removing files from the cart may result in the cart not being updated as expected.
• The aggregated MAF generated using the Cohort Level MAF tool is missing the tumor_bam_uuid column. The tumor_sample_uuid and case_id should be used for reproducibility until the tumor_bam_uuid has been added.
• In both the Sequence Reads and BAM Slicing Download tools, the number of available BAM files may be overcounted when a cohort filter is in use.
• Gene/mutation sets created from the tables in the Mutation Frequency tool may contain 0 genes/mutations if the cohort has Available Data filters or Biospecimen filters.
• The TSV of the cases table may not contain the expected tabs.
• In the Repository and cases table, the case ID search field is case-sensitive. If the search does not return the expected results, try changing the input to uppercase as case IDs are most commonly uppercased.
• When the Cohort Comparison tool is loading, the loading spinner may be displayed above the other areas of the Analysis Center.
• The Slide Image Viewer will display a black image temporarily if a user zooms in on a slide then switches to another slide.

Release 1.8.0

• GDC Product: GDC Data Portal
• Release Date: August 22, 2017

New Features and Changes

Major features/changes:

• A feature that links the exploration and repository pages was added. For example:

  • In the exploration page, cases with a specific mutation could be selected. This set could then be linked to the repository page to download the data files associated with these cases.
  • In the repository menu, the user can select cases associated with specific files. The set could then be linked to exploration page to view the variants associated with this set of cases.

• Users can now upload a custom gene list to the exploration page and leverage the GDC search and visualization features for cases and variants associated with the gene set.

• Filters added for the gene entity page. For example:

  • Clicking on a mutated gene from the project page will display mutations associated with the gene that are present in this project (filtered protein viewer, etc.).
  • Clicking on a mutated gene from the exploration page will display the mutations associated with the gene filtered by additional search criteria, such as "primary site is Kidney and mutation impact is high".

• UUIDs are now hidden from tables and charts to simplify readability. The UUIDs can still be exported and viewed in the tables using the "arrange columns" feature. In the mutation table, UUIDs are automatically exported.

• Mutation entity page - one consequence per transcript is shown (10 rows by default) in the consequence table. The user should display all rows before exporting the table.

Bugs Fixed Since Last Release

• Exploration
  • Combining "Variant Caller" mutation filter with a case filter will display incorrect counts in the mutation facet. The number of mutations in the resulting mutation table is correct.
  • Mutation table: it is difficult to click on the denominator in "#Affected Cases in Cohort" column displayed to the left side of the bar. The user should click at a specific position at the top of the number to be able to go to the corresponding link.

• Added a link to Biospeciment in the Case entity page

Bugs Fixed Since Last Release

• General.
  • Not possible to use the browser's back button after hitting a 404 page
  • 404 page missing from Legacy Archive Portal
  • Table widget icon and export JSON icon should be different
  • Download SRA XML files from the legacy archive portal might not be possible in some context
• Data and facets
  • Default values for age at diagnosis is showing 0 to 89 instead of 0 to 90
  • Biospecimen search in the case entity page does not highlight (but does bold and filter) results in yellow when title case is not followed
  • Table sorting icon does not include numbers
  • '--' symbol is missing on empty fields (blank instead), additional missing fields identified since last release.

Known Issues and Workarounds

• General
  • When no filters are engaged in the Legacy Archive or Data Portal, clicking the Download Manifest button may produce a 500 error and the message "We are currently experiencing issues. Please try again later.". To avoid this error the user can first filter by files or cases to reduce the number files added to the manifest.
  • After successful authentication, the authentication popup does not close for Internet Explorer users running in "Compatibility View". This only impact users at the NIH. Workaround is to uncheck "Display Intranet sites in Compatibility View" in Internet Explorer options. Alternatively, refreshing the portal will correctly display authentication status.
  • When user login from the advanced search page, the login popup does not automatically close
• Cart
  • When removing a file from the cart and clicking undo, GDC looses track of permission status of the user towards this file and will ask for the user to log-in again.
  • Counts displayed in the top right of the screen, next to the Cart icon, might get inconsistent if files are removed from the server.
  • Download File Metadata button produces incomplete JSON output omitting such fields as file_name and submitter_id. The current workaround includes using the API to return file metadata.
• Annotations
  • Annotations notes do not wrap to the next line at the beginning or the end of a word, some words might be split in two lines
  • Sorting annotations by Case UUID causes error
• Web Browsers
  • Browsers limit the number of concurrent downloads, it is generally recommended to add files to the cart and download large number of files through the GDC Data Transfer Tool, more details can be found on GDC Website.
  • Internet Explorer users are not able to use the "Only show fields with no values" when adding custom facets
  • The GDC Portals are not compatible with Internet Explorer running in compatibility mode. Workaround is to disable compatibilty mode
