cuffmerge error
Hi, I am confronted with some errors when doing cuffmerge analysis.

/home/bin/cuffmerge -g Ptrichocarpa_156_gene.gff3 -s Ptrichocarpa_156_hardmasked.fa -p 10 assemblies.txt

[Wed May 30 09:48:20 2012] Converting GTF files to SAM
Error: gtf_to_sam not found on this system. Did you forget to include it in your PATH?

I checked very carefully with my directory /home/bin and found that gtf_to_sam is actually in this directory. I cannot understand why the software cannot find it.

Sorry for my naive questions.

Any comments are very appreciated.

You need to type the following command in your terminal:

Thanks wangli, but that doesn't appear to be the problem. Any other ideas?
