Shorah: UnboundLocalError: local variable 'end' referenced before assignment

[ptapiaisp]

Hi, I am running shorah (installed with conda) and I am getting an error, my command line is:

shorah shotgun -b my_bam.bam -f CoV.fasta -a 0.1 -w 201 -x 100000 -c 10 -r CoV:1-29903

Error is: Traceback (most recent call last): File "/miniconda3/bin/shorah", line 14, in main() File "/miniconda3/lib/python3.7/site-packages/shorah/cli.py", line 196, in main args.func(args) File "/miniconda3/lib/python3.7/site-packages/shorah/cli.py", line 75, in shotgun_run shotgun.main(args) File "/miniconda3/lib/python3.7/site-packages/shorah/shotgun.py", line 452, in main runlist = win_to_run(alpha, seed) File "/miniconda3/lib/python3.7/site-packages/shorah/shotgun.py", line 336, in win_to_run del end UnboundLocalError: local variable 'end' referenced before assignment

any idea?
