GSEA error 1005

Hello

I am trying to analyze human gene sets for their expression in tumor. I am facing an error saying "The collapsed dataset was empty when used with chip:ftp.broadinstitute.org://pub ..."

Could someone please help me understand what could be causing this error? and how could I successfully analyze my data.

Do you really need to use the collapse option? I mean if it is data for human samples and you already have gene symbols as the input, why don't you select the no_collapse option?

And one more thing if you are selecting the collapse option you have to select the appropriate chips option and in your case, I guess it should be Human_Gene_Symbol_*
