hello,
I am trying to run ssGSEA, but am encountering the following error:
Error in vector(length = gene.set.size, mode = "character") : invalid 'length' argument Calls: ssGSEA.cmdline Execution halted

I know my gct file works because I was able to run the GSEA hallmark gene set. I am not sure what is wrong with my gmt file (attached). Could you please advise?

thank you,
Vijay

Hi Vijay,

The issue might be with the quotes and commas in the gene set names in your file, I’d recommend removing those and trying again
