Thanks for reaching out. We haven’t been able to reproduce this issue from our end. Could you please share the full command and log file with passing flag “–x3” and “–verbose” with us? If by any chance that you can share your input data with us, that would be very helpful for our debugging too.
Thanks for sharing the log file. The command and debug messages look fine. It seems to be a corner case that we are handling properly.
Could you please share your input data with us if possible? Ideally the fasta and the bam with a few chromosomes at the beginning that can reproduce the error. If it’s public data, a link to it would be enough.
Thank you so much for sharing the data! Confirmed that we can reproduce the issue, and it has been fixed. This update will be included in the coming 4.8 release in Oct.
