CNV from TCGA data

Question

[emiliakozlowskaa]

Hi,

I need to analyze copy number variation data from TCGA. I have downloaded all data but several things are not clear with the data.

1. The first question is why we have 4 files per patients? Which file I should look at?
2. I have for example sample id SOURS_p_TCGAb22_SNP_N_GenomeWideSNP_6_C01_529802. How to link sample id to TCGA barcode? I would like to link CNV to clinical data thus conversion from sample to barcode is necessary. How I can do it?

Thank you in advance for your help.
