Hi there,
I encountered an error when running pyscenic ctx with the following code, and I would like to know the cause of this error. Thank you!

ncore=20
disease_name="MM_with_HD_eRNA_count"
loom_file="/users/cuiyiran/RData/DEG_enhancer/Fig3/loom_file/${disease_name}.loom"
output_base="/home/cuiyiran/data/caixp/SCENIC/output/${disease_name}"

short_name="${disease_name%_eRNA_count}"
step1_out="${output_base}/step1_${short_name}_grn.tsv"
step2_out="${output_base}/step2_${short_name}_ctx.tsv"
auc_out="${output_base}/${short_name}_SCENIC.loom"

##step2 CTX
