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.

How is survival analysis calculated?

Survival analysis in the GDC uses a Kaplan‑Meier estimator:

  • S(t ) is the estimated survival probability for any particular one of the t time periods
  • n is the number of subjects at risk at the beginning of time period t
  • d is the number of subjects who die during time period t
