Kidney Renal Clear Cell Carcinoma: Preprocessing of clinical data
Maintained by TCGA GDAC Team (Broad Institute/Dana-Farber Cancer Institute/Harvard Medical School)
Overview
Introduction

The clinical information for each TCGA tumor sample is stored in a xml file. Patient ID, tumor and treatment info are entries of the xml file. These xml files have been preprocessed for further analysis.

Summary

Clinical data for tier 1 clinical variables are generated.

Methods & Data
Work Flow

1. Each xml file is converted to a tab-delimited text file by our R package.

2. All text files are aggregated into one big table by the Clinical_Aggregate_Tier1 pipeline. The 1st column of the table is the entry name of the xml file and the rest columns are the associated data for samples.

3. Data for the tier 1 clinical variables are extracted by the Clinical_Picker_Tier1 pipeline.
