Hello,

I have a problem with Cuffdiff, having successfully executed Tophat, Cufflink and Cuffmerge on RNAseq data as part of a tutorial. Here is the error message I received.

Fatal error: Exit code 1 () Error: sort order of reads in BAMs must be the same

I tried to run Cuffdiff twice and it did not work.

Any suggestions would be appreciated.

Thanks,

Katie

Hello,

The error is coming up because some of the Tophat jobs were mapped against papHam1 (the default in the target database/genome select list on the tool form) instead of actively selected to be hg19.

Rerun: the Tophat jobs to use hg19 instead, then the derivative Cufflinks, Cuffmerge, and Cuffdiff jobs.

Everything else in your procedure looks great!

Thanks! Jen, Galaxy team
