I downloaded fpkm-type RNA-seq data from Genomics of Drug Sensitivity in Cancer. Then, arranged data for GSEA of my own purpose and saved as txt file. txt file was uploaded successfully and retrieving Gene Sets database file was also done with no problem. after that, it seemed analysis was going on for a while, but resulted in error with "col:33 > matrix's fColCnt:33" message. I guessed there was difference between the number of cell line and gene expression data of each gene. But, confirming repeatedly, I couldn't find any difference. Each gene looked having 33 expression data which is as same number as cell lies I prepared for this analysis. I might have wrong interpretation about error message, but I'm not sure. Someone, please help to solve this problem.
Without code and data this is almost impossible to answer.
