1: In .GSEA(geneList = geneList, exponent = exponent, minGSSize = minGSSize,  :
  We do not recommend using nPerm parameter incurrent and future releases
2: In fgsea(pathways = geneSets, stats = geneList, nperm = nPerm, minSize = minGSSize,  :
  You are trying to run fgseaSimple. It is recommended to use fgseaMultilevel. To run fgseaMultilevel, you need to remove the nperm argument in the fgsea function call.
3: In preparePathwaysAndStats(pathways, stats, minSize, maxSize, gseaParam,  :
  There are ties in the preranked stats (0.22% of the list).
The order of those tied genes will be arbitrary, which may produce unexpected results.
