Analyze Data

The GDC provides user-friendly and interactive Data Analysis, Visualization, and Exploration (DAVE) Tools supporting gene and variant level analysis that allows researchers to:

  • Visualize most frequently mutated genes and view most frequent somatic mutations for a project
  • Plot all cases for a project in an OncoGrid and visualize the top 50 mutated genes affected by high impact mutations
  • 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 using an interactive Protein Viewer
  • View the cancer distribution as evidenced by the number of cases affected by the mutation across all projects
  • Build cohorts and perform gene and variant level analysis on the cohort
  • Compare custom gene or case sets by visualizing set similarities and differences

Data Analysis Policy

The GDC provides policies for publishing the results of analyzed data.

Data Harmonization and Generation

GDC variant calling pipelines generate high level data for analysis. Variant calling pipelines are implemented using data processing software and algorithms selected in consultation with the expert genomics community.

How is survival analysis calculated?

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

Survival Analysis Formula

  • 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
