Hi all,

I am trying to run the gseGO function in clusterpofiler to look at GSEA of my list of differentially expressed genes. The structure of the data is the following:

X    baseMean log2FoldChange     lfcSE      stat      pvalue        padj

I perform the following transformations to extract the gene list (I have tried this with the ensembl IDs as well, but the error is the same)

gene_list <- df_GSEA$X  # Assuming 'X' contains Ensembl gene IDs

gene_list = sort(gene_list, decreasing = TRUE)

gse <- gseGO(geneList=gene_list, 
             ont ="ALL", 
             keyType = "SYMBOL", 
             nPerm = 10000, 
             minGSSize = 3, 
             maxGSSize = 800, 
             pvalueCutoff = 0.05, 
             verbose = TRUE, 
             OrgDb =, 
             pAdjustMethod = "none")

But I keep getting this kind of error:

preparing geneSet collections...
--> Expected input gene ID: VCX,PPARD,EDDM3A,MAMLD1,RAD50,SUPT6H
Error in check_gene_id(geneList, geneSets) : 
  --> No gene can be mapped....

When I check the gene list, it contains the correct format of gene names, so I am not sure why it's not recognizing them.

Does anyone have a suggestion on how to fix this?

Thanks a lot, Ana

Have a look at the documentation :

geneList argument should be an order ranked geneList. Authors detail here how to format a ranked geneList :

"GSEA analysis requires a ranked gene list, which contains three features:

numeric vector: fold change or other type of numerical variable

named vector: every number has a name, the corresponding gene ID

sorted vector: number should be sorted in decreasing order"

Ahh thank you, that fixed it!
