I am looking for a tool to convert SAM to sorted BAM (sorted by the coordinates, such as with samtools sort or picard's SortSam).

Hi,

Samtools sort is available in the ToolShed for use in a local or cloud Galaxy:
http://toolshed.g2.bx.psu.edu/view/iuc/samtools_sort

A ticket to add this tool to the public Main Galaxy instance http://usegalaxy.org is open here: https://trello.com/c/PxiesIK6

Main has a tool that sorts by the ordering of the reference genome (Reorder SAM/BAM) but this is not quite the same function.

And finally, SAM files can be coordinate sorted, then converted to BAM format, but this will not change the sort status in the header. Still, it is often enough for many tools. A sample workflow is below. If starting with a SAM file, modify the workflow to eliminate the initial BAM-to-SAM conversion:

Best, Jen, Galaxy team

samtools_sort is exactly what I needed, thanks! I was searching in the toolshed under "sam" and "bam", didn't think of this.

Jen, we need to include samtools sort into the samtools suite and in main :)

Agreed, super useful. The ticket above is open with high priority status. This may be just pending prioritization. All - cast your vote in Trello! Jen
