Hello

I am new to RNA-Seq analysis and am struggling a bit with setting up the CuffDiff

I have two conditions and for each I have 3 replicates. I want to compare significantly different expression between conditions but also between replicates within conditions.

Can I run this all at once and if so how?

I get the impression that I need to run CuffMerge first to put all 6 datasets together into one file but after running this with the two conditions (containing 6 datasets each), there seems to be no distinction between replicates.

Should I run the 6 'assembled transcripts' files from Cufflinks separately against all three replicates of each condition? That seems to lead to many files.

Hope that makes sense!

Thanks

Tom

Hello,

Try the Cuffdiff option to "Include Read Group Datasets" with Cuffdiff. This might produce the data you need the most.

Another alternative for DE is to use a count-based tool like Deseq2.

Please see the RNA-seq tutorials here for example workflows: https://galaxyproject.org/learn/

Thanks, Jen, Galaxy team
