Hello all, I was trying to perform GSEA for a dataset using the `fgsea` R package. The code I used was `fgseaRes <- fgsea(pathways = pathways, stats = ranks, minSize = 5, maxSize = Inf)` I received an warning

Hi everyone I dont really have problems running fgsea itself but im trying to understand what gseaparam argument in fgsea() means. The vignette says it's a GSEA weight parameter...but weightage of what? each fgsea term? and to what exactly hope to hear some clarifications; tried googling it's still not clear to me

Hi All i ran fgsea() successfully; my sample is brain tissue but im getting quite a few fgsea GO hits that describe other relatively far off...tissues processes -like digestive system.. etc. i was wondering if there's a possibility to run my fgsea just on brain related GO processes? would appreciate any advice

Hi, &nbsp; Does&nbsp;fgsea&nbsp;order the stats argument? What I'm currently doing is order ordering the effect (i.e. log treatment vs. control fold...changes) but their p-vaiues and passing that to fgsea. But the fgsea code suggests it re-ranks stats so the p-value ranking is lost. Is that the case? and if so is there any way to
