There is not a "the" CNV file. There is a CNV file for each patient - so around 1100 according to this.

Is that what you want?

For each patient there are 5 files (in the CNV column): The file "BRCA.focal_score_by_genes.txt" contain CNV scores for each gene in ALL BRCA samples. The 4 other files (all starting with "BRONZE") are two pairs of files: Two of them are with and without masked regions according to this. The two files for for each region appear to be different versions of the analysis (F9 vs F6) which I cannot find what the difference is. I would probably write and ask them.

Update: 8th March 2019:

  • Link to GCD data portal updated
  • Updated description of files
