Thanks for the response Jen!

Answers to your questions below. 

  1. It should be the newest version of Galaxy
  2.  We did make production server changes but I'll check the admin part again
  3. This might be the problem.  I tried to install package_samtools_0_1_19 but it failed, then I installed package_samtools_0_1_18 which succeeded, and lastly I installed bam_to_sam
  4. I have not tried the main galaxy instance yet. 
I did mean the "same" file. I just turned off autoscaling to simplify things. 
I'll get back to after: unistalling  package_samtools_0_118 and bam_to_sam and then just installing bam_to_sam and reviewing the how our production server is set up.
Thanks 
Mike

Subject: inconsistent BAM-to-SAM behavior

Hi Mike,

I am moving this over to the galaxy-dev@bx.psu.edu mailing list as it concerns a local install. This is the best way to make contact with others working with the same type of Galaxy.
https://wiki.galaxyproject.org/MailingLists

A few things to provide more context that will help with troubleshooting:

1 - Are you running the most current version of Galaxy?
      https://wiki.galaxyproject.org/DevNewsBriefs (Nov 4, 2013)

2 - The local has some of the initial production server changes made?
      initial install: http://getgalaxy.org
      next steps are under: https://wiki.galaxyproject.org/Admin
      in particular: https://wiki.galaxyproject.org/Admin/Config/Performance/ProductionServer

3 - You installed SAMTools from the Tool Shed? The config is correct? And are running the latest version?
      https://wiki.galaxyproject.org/Tool%20Shed#Installing.2C_maintaining_and_uninstalling_tool_shed_repositories_within_a_Galaxy_instance
      https://wiki.galaxyproject.org/Admin/Config/Tool%20Dependencies
      https://wiki.galaxyproject.org/Admin/Tools/Tool%20Dependencies

4 - When you run the same dataset(s) through on the public Main Galaxy instance at http://usegalaxy.org, is it successful or does it fail?

I wasn't sure if you meant that the same file will fail and then pass, or if some fail and some pass. If you could clarify that, it would help. It could mean the difference between a processing problem (pointing to a config or other issue) and a simple memory problem (where allocating more could help). Please keep all replies on the mailing list with a cc.

Thanks!

Hi,

I have run some top hap output through the samtools BAM-to-SAM wrapper. It creates the SAM file about 50% of the time. The rest of the time it makes an empty file. In this case if I just rerun it often works. I was wondering if anyone else has seen this behavior. I am using a cloud server and think  I might need to change some settings. This causes my workflow to fail for many libraries so I also interested in any workarounds anyone has figured out.
Thanks in advance for any help.
Cheers
Mike
