Thank you for the wonderful tool! When I want to make my own GRN, get error. My network can't download ref_genome so
I manual download https://hgdownload.soe.ucsc.edu/goldenPath/mm39/bigZips/mm39.fa.gz and

ref_genome = ".mm39.fa.gz"

get error and follow the tips

gunzip mm39.fa.gz; bgzip mm39.fa

then again

ref_genome = ".mm39.fa.gz"
peaks = pd.read_csv(".processed_peak_file.csv", index_col=0) #my own peak make before
peaks.head()

when I set the ref_genome = "mm39" before tfi.scan still get same error.
Would you and some one give some tips? thanks a lot!

anybody get same issue?
