Couldn't run pyscenic aucell

[baijiexu]

Hi,
When I run pyscenic aucell, I get the error here.

pyscenic.cli.pyscenic - ERROR - A gene signature must have at least one gene.

I really don't know how to do next. I could run successfully for pyscenic grn and pyscenic ctx

However, I was stuck at pyscenic aucell this step. Could you help me figure it out?

Here is all the information:

pyscenic aucell simcre_ctrl.loom simcre_ctrl_reg.csv --output simcre_ctrl_SCENIC.loom --num_workers 20

2022-09-30 23:16:34,077 - pyscenic.cli.pyscenic - INFO - Loading expression matrix.

I appreciate, thank you so much!
