[galaxy-dev] About an additional tool

Hi there, I know Galaxy already has a SAM-to-BAM converter, but part of my exercise/task is to incorporate a script that uses samtools' view command. I get this error: [samopen] SAM header is present: 66338 sequences. according to Galaxy. But this might not be an error at all. Is there any way that I could tell Galaxy to ignore this and just continue with the script? Thanks in advance! Any help would be greatly appreciated. CL
