Non human-readable error for test data SRR6000626

[serge2016]

Hello!
Thank you for this great tool!

I think there is an error when I run xHLA on some the bam-file with the alignment of target reads. It is some kind of test data in my case, that is used in a big pipeline with many tools. I suppose that region of interest is absent in my test data, but I think the error should be more human-readable.
