Ok, I think I understand the line:

beginning merge: bwa mem /home/ralonso/BiB/Galaxy/data/Cclementina_v1.0_scaffolds.fa /home/ralonso/galaxy-dist/database/files/000/dataset_8.dat > /home/ralonso/galaxy-dist/database/files/000/dataset_94.dat 2> /dev/null

it refers to the original command, so everything is fine with this line. The other problem still remains

Regards, sorry for the confusion

Hello again,

this is something that I consider important, when I see the log I see this output:

galaxy.jobs.runners.tasks DEBUG 2015-02-25 11:33:30,989 execution finished - beginning merge: bwa mem /home/ralonso/BiB/Galaxy/data/Cclementina_v1.0_scaffolds.fa /home/ralonso/galaxy-dist/database/files/000/dataset_8.dat > /home/ralonso/galaxy-dist/database/files/000/dataset_94.dat 2> /dev/null

I think the merge should be done with samtools. I don't know how is this programmed in Galaxy, but I didn't indicate anywhere the path to samtools, is it maybe the problem related with this?

Thanks a lot,

Regards

Hello,

I just changed for the CDATA format, but the problem still remains. When I split by 2, there is no problem, but when I go for 3, it happens the problem commented before. Here it is the link to the sam/bam file:

Good.

One minor improvement would be to escape the ">" as "&gt;" in
your XML, or use the CDATA approach documented here:

This sounds to me like there may be a problem with SAM merging?
Could you share the entire example_split.sam file (e.g. as a gist
on GitHub, or via dropbox)?
