Default RNA Star with and without GFF problems

Actually, I am having a lot of problems with this particular analysis, but lets start with this. I have some good RNA, deep read count, triplicate biological replicate data from Drosophila heads - small genome and well annotated. SHould be easy, right?

I have tried the Ensamble and Flybase files for mapping with various results. Most important is that for Flybase I can't seem to get any GFF3 or GTF files to work with the Fasta file using RNA Star (in Galaxy). For the Ensemble data, I can get them both to work, but in the end I get very few significant hits - but I already know some of our previous analysis - which I won't get into - revealed differentially expressed transcripts that we showed by both qRT-PCR and proteomic analysis are real - i.e. I believe them more than any bioinformatic proof.

Here is the Ensemble repository I used Ensemble FTP

Here is the Flybase repository I used Flybase FTP

Table of RNA Star Mapping Trials

Any help appreciated. Trying to do both CufDiff and DEseq analysis on this data.

Hi tonup69,

Might be best to post the actual error you are getting - why won't RNA Star accept your files?
