Analyze Data

The GDC provides an array of interactive, web-based Analysis Tools for performing in-depth gene- and variant- level analyses. The workflow is cohort-centric, meaning analyses are specific to a researcher's cohort of interest.

  • Build cohorts and perform gene and variant level analysis on the cohort
  • Visualize most frequently mutated genes and somatic mutations for a cohort
  • Visualize a matrix of the top most mutated cases and genes affected by high impact mutations in a cohort
  • Perform a survival analysis for cases with a mutated form of a certain gene and cases without the mutation
  • Visualize mutations and their frequency across cases mapped to a graphical visualization of protein-coding regions
  • Visualize the top most variably expressed genes in a cohort
  • Visualize sequencing reads for a given gene, position, SNP, or variant
  • Use clinical variables to perform basic statistical analysis of a cohort
  • Compare custom gene or case sets by visualizing set similarities and differences

Data Analysis Tools

The GDC provides interactive, cohort-centric tools for analyzing genomic and clinical data.

Data Analysis Policy

Policies and guidelines for appropriate use of data, are provided by the GDC whether open- or controlled- access.

Data Harmonization and Generation

The GDC developers best-in-practice pipelines for processing the most common molecular platforms. Variant calling, gene expression analysis, and other pipelines are implemented using software and algorithms selected in consultation with experts in the genomics community.

Why did the GDC remove SomaticSniper?

The SomaticSniper whole exome variant caller was one of the first generation somatic mutation callers developed by the scientific community. It works the best with blood cancer that has high level of tumor-in-normal contaminations, but is often overly permissive for solid tumors. Since our first data release in 2016, the GDC has gradually adopted newer tools or new tool versions, and has transited the focus of somatic variant calling from any single caller to multi-caller ensemble.

After comparing ensemble calls with and without SomaticSniper and also receiving feedback from the authors of SomaticSniper, the GDC decided to remove this tool from our production in Data Release 35. The GDC still maintains other four whole exome variant callers, including MuSE, MuTect2, Pindel, and VarScan2.
