Hi Olivier, Did you try to run Cuffcompare (part of Cufflinks) on your results? According to the Cufflinks manual (http://cufflinks.cbcb.umd.edu/manual.html ): transfrags you assemble. The program cuffcompare helps you:
- Compare your assembled transcripts to a reference annotation [...]
In the Galaxy version of Cuffcompare, I think that you can provide a reference annotation file using "Use Reference Annotation:", which will be compared to your results with Cufflinks. It makes an "union" of the transcripts obtained with Cufflinks with the annotation file (both in *.gtf format). You can then obtain a transcript identifier for those already annotated. It also provides a class code for the transcripts, which can inform about a potential isoform for example. Hope this helps.

Hello
I am using Galaxy to analyse RNA-seq libraries made from chicken cells.
I just groomed my sequences, passed them through TopHat and then Cufflinks.
This worked well and in the end I get a list of genes and their respective FPKM values.
My only problem is that the names of the genes do not appears in the listing, they are simply reference as "CUFF.1, CUFF.2, " etc?
Could you please tell me how I could obtain gene names? (I went through the FAQ and could not get the answer).
Sincerely
Olivier
