hi i have uploaded gff format GRCh37.p13 in glaxy. however i am unable to see it on doing any analysis like for tophat and cufflink. how can i do it. how do i convert it to gtf for using it as a reference genome for tophat. it is a human genome. thanks a lot. regards

Is it really a GFF file or does Galaxy just think it is (Galaxy will label GTF files as GFF when you upload them unless you explicitly tell it that the file has GTF format)? If it's really a GTF file then just upload it again and explicitly select "GTF" as the file type.

thank you devon. i will try again. in tophat using full parameter list i am choosing use gene annotation model. in that it is not showing grch37 although it is showing it in my history of galaxy account. i hav echosen hg19 as reference genome. how to go about it. thanks

There is a Tool that does this now

I used it to change a .GFT file to a .GFF3 file. But I think it goes the other way.

It is on usegalaxy.org

Cheers Guy

Hello,

There are no tools to transform between these three formats: GFF, GTF, or GFF3.

Double check the actual file type and reload as Devon suggests or change the assigned datatype directly to be correct and recognized by tool forms as appropriate input.

Thanks, Jen, Galaxy team
