Hi all,

I am working on drug screens, particularly, looking at the drug’s AUC against the gene expression/copy number. Comparing the **csv files** in the download site with the **depmap data explorer** , the csv files only has 16383 genes whereas the depmap data explorer showed 19160 genes in total. Based on my analysis, among these 2, only 15573 genes intersect/overlap and there are 3587 extra genes in depmap data explorer. This happens in all 3: genecn.csv, expression.csv and expression\_full.csv. Is there an explanation to this?

Hi!

Thanks for your feedback!  
I am assuming you are downloading the csv files from the DepMap Public datasets. Do you mind going over how you are getting the genes in data explorer so I can reproduce this error and look into it? Screenshots would be very helpful. Thanks!
