I tried to align against new brand Maize genome (now at Galaxy), and the same messages. I also converted the BAM file to SAM, but the same. Any advice? What was wrong? Thanks in advance.

Re: [galaxy-user] Trouble with RNAseq analysis
Cristian, The is a formatting character; what needs to match is the string after the in the genome file and the entries in the contig column of your GTF. Your GTF is quite different that your genome file; your genome file has 10 contigs labeled by number, but your GTF has many, many contig names labelled by numbers and names. For Cufflinks to work, you can either (a) turn off bias correction or (b) restrict entries in your GTF to those that match your reference genome. Finally, please reply all to emails so that all emails remain on list for archival and community purposes. Thanks, J. On Mar 30, 2011, at 12:02 PM, Cristian Rojas wrote: Thanks Jeremy.

Re: [galaxy-user] Trouble with RNAseq analysis
Hi Jeremy, I turned off the bias correction and didnt use the genome option, just put the refernde (GTF file), but still the problem.

Re: [galaxy-user] Trouble with RNAseq analysis
I tried agaian and the same problem. I tuned off the bias correction but mantained the GFT file. May be this is the problem? I didnt find your history.
