I am just starting to get familiar with Galaxy and bumped into a problem of which I don’t know how to handle. I generated a collection of dataset pairs and run Bowtie2 on that collection. Now, I am trying to run CleanSam on the generated bam files but an error occurs:

I visualized the bam files with IGV and was not able to see any alignments. Does that mean that something with Bowtie2 went wrong? What can I do to solve this problem? Unfortunately, I don’t have any background in bioinformatics.

Thanks a lot.
