IndexError when running advntr addmodel

[jsquaredosquared]

Issue:
I get an IndexError when I try to run advntr addmodel. What can be done to fix this error?

Version:
adVNTR 1.3.3 (downloaded using conda)
(Note: I have tried to install the latest GitHub version but it fails to build because of a Cython CompileError.)

Command:

advntr addmodel \
-r ~/[...]/hg38_no-alt-no-random.fa \
-c 18 -s 57024495 -e 57024955 \
-p GTTATGTCCCTTATAGAATTTCACATATCCCTATTCTCAGACAGGAATAGGGATATGTGAGCTATGATA \
-g WDR7 \
-m vntr_data/hg38_selected_VNTRs_Illumina.db

Output:
