TCGA Data Level

1

Raw

• Low-level data for single sample
• Not normalized

2

Processed

• Normalized single sample data
• Interpreted for presence or absence of specific molecular abnormalities

3

Segmented/ Interpreted

• Aggregate of processed data from single sample
• Grouped by probed loci to form larger contiguous regions (in some cases)

4

Summary/Regions of Interest (ROI)

• Quantified association across classes of samples
• Associations based on two or more
  • Molecular abnormalities
  • Sample characteristics
  • Clinical variables
