Hi My cuffdiff run does not continue , it stops and says FATAL error exit code 139(),
My function parameters are
Condition I 2 replicate bam files ( my replicate alignments)
Condition II 2 replicate bam files ( my second set of replicate alignments or second experimental conditioN)
GTF file provided was actually produced by cuffmerge of the GTF files generated from cufflinks is 0.3 Gigs
Each bam file is between 6-7 Gigs
I would appreciate any kind of help

Hello,
Where are you working? If http://usegalaxy.org, please send in a bug report that includes a link to this post and we can review/provide feedback. If not working on Main, please see if you can replicate this there or send in more about the reported error message.
Just so you know, conditions should be named with alphanumeric characters and (optionally) underscores, no spaces. Also, segmentation faults can indicate that a tool requires more compute resource than is available to the process (the job running the tool).
Thanks, Jen, Galaxy team
One more comment , the spaces added here for the identifiers were not included in the actual run , the actual run has no spaces
Hello,
The tool is a confirmed mismatch for the tool form. A github issue has been opened to correct the tool form. Progress on the correction can be followed here: https://github.com/galaxyproject/tools-devteam/issues/170
Thank you for reporting the issue and sending in an example. For now, the jobs you have running with a single BAM input is the proper usage (meaning, ignore the option to submit multiple). But if you have any problems with that, please let us know.
We appreciate the detective work! Jen, Galaxy team
Jen !
So Technically I cannot use the galaxy , for differential expression if I have replicates , is that what I read??
I just want to make sure so I can give feedback to "my boss"
Thanks

No, you can definitely use replicates with this pipleline. Just do the Cufflinks and Cuffquant steps on the individual samples. Cuffmerge then combines them all into the reference GTF. Finally, put all together in conditions as replicates on the Cuffdiff tool form along with the Cuffmerge GTF result. This is basically the same RNA-seq pipeline as was used earlier, with an extra normalization step (via Cuffquant).
Does this help? Jen
Cool will do the reading on cuffcuant to see what kind of parameters to give and will give it a shot. Thanks for sticking around ;)
I know this might be very technical, but I rather ask, what is the difference between the gtf file that comes from cuff merging the files out of cufflinks, vs, the gtf file that would be got out of cuffcuant?my guess is that it's an aditional step in the normalization or something . Thanks a lot all this has been an eye opener for me
