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?
