KeyError on RNA-seq data

Hey Daniel,

I met this error when try to run bamsnap on a rna-seq bam file:

Process proc 1:

KeyError: 32793279

Any suggestions on this? Thank you!

Hi Daniel,

I run into the same issue as Simon when running Bamsnap on RNA-seq bams. Thanks for developing Bamsnap, it's incredibly useful and easy to use for visualizing bams. Please let us know how it would be possible to tackle the KeyError.

Many thanks,

Katerina

I too have the same issue, using RNA-Seq data. It is possible this is because of the large junctions in the middle of reads?
