Hello!
I have run modulize on a few data sets and was looking into alternative 3' splice site usage. When I looked into the alt3prime.tsv output file I noticed that in a particular subset of the data (cases where the gene is minus strand and the spliced_with is E1) it appears that the reported reference_exon_coord and spliced_with_coord are identical and I believe are the coordinates for the intronic space between the reference and spliced_with exons, rather than the exons themselves.
For the other 3 combinations of strand and spliced_with this does not appear to be an issue.
I wanted to double check to make sure this is not something I could have done on my end somehow or has been resolved in later releases.
Thanks in advance!
Best,
David McWatters
