Thanks for your help

I did a RNA-seq using galaxy, and find out the transcripts and gene 
differential expression is identical, furthermore, rest of the file such as 
CDS, TSS, Promoters etc..are empty files, does not matter if I use annotation 
file from UCSC refgene gtf file or without annotation file....

What is the possible reason?

Regards.

Hello,

Cuffdiff does only pairwise differential expression testing, so each DE test 
will consider two groups, not three or more. However, Cuffdiff does iterate 
through and provide data for all possible group pairings. E.g.

A vs B
A vs C
B vs C

Best,
