Welcome @Rafael_Lema

iGenomes hosts a quality GTF file for UCSC’s sacCer3 genome.

How to get it out of the archive and uploaded to Galaxy is covered in this prior post:

> [@RNA-STAR and hg38 GTF reference annotation](https://help.galaxyproject.org/t/rna-star-and-hg38-gtf-reference-annotation/749/2):
>
> For **iGenomes** , the archive corresponding to the target genome/build needs to be locally downloaded, the tar archive unpacked, and then just the `genes.gtf` data uploaded to Galaxy (browse the local file, or use FTP). Find all available genome/builds here: [iGenomes](https://support.illumina.com/sequencing/sequencing_software/igenome.html)

Thanks!
