error in cuffmerge

Question

[zizigolu]

Hi,

I downloaded gtf and genome.fa for yeast already but after trying many fastq files again I get the same error

May you tell me the reason please?

[andrew.j.skelton73]

probably a chromosome naming mess up. Check the chromosome names for your fasta file, against your input gtf.

[zizigolu]

thank you, but both containing the same chromosome names

[andrew.j.skelton73]

Including the GTF that you ran Cufflinks against?

[zizigolu]

yes I checked
