I would like to get a raw RNA-Seq counts matrix from the results of the Tophat alignment to a reference genome. Figured Cuffquant would do the trick, but what to do with the .cxb file that results?? Why not a .csv file, or at least the option to pick up front? Any suggestions anyone? 

BTW, it would be lovely if it were possible to access htseq from the Galaxy menu and input BAM files and the gtf and get a raw counts matrix out.

Thanks!

Hello,

Use Cuffnorm to obtain a final tabular result file. Cuffquant is performing a portion of the calculations needed for this type of summary, but not all. Also see the Release Notes and Manual for more help.

Thanks, Jen, Galaxy team

Jen,

Cuffnorm normalizes the counts, albeit in a variety of methods, but still the output is still normalized.  I need raw counts for DESeq2 input.  All I want are the alignment counts.  Would be nice if HTSEQ was a part of the Galaxy tools.
