how to use custom genome i.e. E. Coli in epic2 ?

[Ankana001]

Hi, I am using epic2 for my E.coli ChIP-seq data, But it runs with hg19 genome as default, so I used custom genome fasta file which is in the same folder as the data. I am using this following command:
epic2 -t SO_4933_A_CHR1_R1_sorted.bam -c SO_4933_A_INR1_R1_sorted.bam --genome E.coli_BW25113.fasta --false-discovery-rate-cutoff 0.001 -a -o SO_4933_A_enriched_regions.csv

But it's showing me error Chromosomes removed from analysis: NZ_CP064677.1 (and 0 more.)

Traceback (most recent call last): File "/home/ibab/.local/bin/epic2", line 257, in _main(args)
File "/home/ibab/.local/lib/python3.8/site-packages/epic2/main.py", line 35, in _main
effective_genome_length, chromsizes = egl_and_chromsizes(args)

File "epic2/src/genome_info.pyx", line 267, in epic2.src.genome_info.get_effective_genome_fraction
KeyError: 'e.coli_bw25113_75.txt'

how to run this analysis with epic2 for E.coli genome?

You need to use the chromsizes argument where the argument is a file that looks like this:
