[galaxy-dev] samtools_slice_bam/2.0.1 no options available

Hey all, I have a question about the samtools_slice_bam tool in the samtools suite. It seems the references variable remains empty after re-detecting metadata. I now tried sorting the bam in galaxy and manually in samtools, but no references coming up. I also ran a breakpoint in the binary.Bam.set_meta but it doesn't seem to be catched. Any ideas? Thx. Eric
