Description

A dataset containing the Sample Ids from TCGA tumor purity measured according to 4 estimates attributes of 9364 tumor patients

Usage

1

Format

A data frame with 9364 rows and 7 variables:

Sample.ID

Sample ID from TCGA barcodes, character string

Cancer.type

Cancer type, character string

ESTIMATE

uses gene expression profiles of 141 immune genes and 141 stromal genes, 0-1 value

ABSOLUTE

uses somatic copy-number data (estimations were available for only 11 cancer types), 0-1 value

LUMP

(leukocytes unmethylation for purity), which averages 44 non-methylated immune-specific CpG sites, 0-1value

IHC

as estimated by image analysis of haematoxylin and eosin stain slides produced by the Nationwide Childrens Hospital Biospecimen Core Resource, 0-1 value

CPE

derived consensus measurement as the median purity level after normalizing levels from all methods to give them equal means and s.ds, 0-1 value
