Where to get human reference annotation in gff3 or gtf format?

I need a link for the human reference transcriptome in gff3 format

Hello @jananis

Gencode is one choice that I know of. It would be a match for the UCSC-sourced human reference genomes indexed at most public Galaxy servers. UCSC also has this data to match the reference annotation they host.

More help

Here is the link that I used to download the human reference genome.
