Error when running MIDAS on KEGG metabolism gene sets

[dBenedek]

Hello,

MIDAS runs perfectly when running on the example gene sets, however, when running on KEGG metabolism pathways, I get the following message:

[Info] Calculate edge activty & determine differentially activated subpaths

Pathway set file:

hsa04110	Cell_cycle
hsa04010	MAPK_sig
hsa04151	PI3K_AKT
hsa00010	Glycolysis_gluconeog

Trying with other KEGG metabolism pathways gives the same error messages.
I am attaching the full log file (nohup).

I would appreciate your help,
Benedek
