[maker-devel] GFF3 file format

[Fields, Christopher J]

If I recall, from a BAM you would need to run a reference-based assembly on these data (e.g. Cufflinks2 or StringTie) to get this; you can also use Trinity for ref-based assembly.  But I always choose the route of a full de novo assembly (again, Trinity or similar) when possible, doing some basic cleanup (e.g. remove low confidence transcripts) and bring them as EST evidence.

Hi Maya,

I'm not sure what MAKER's requirements are in this regard--I'm forwarding this to their mailing list.

Hi,

I have RNA-seq data, and genomic data that I want to annotate using maker.

From what I understood, I need to genarate a gff3 file format from the RNA-seq mapping sequences. I had mapped the RNA sequences to the genome using bowtie and tophat. However, I still do not know how to take these format and convert them to a gff3 file that I can them use in maker as annotation evidence

I saw the wiki page, that did not mention how to make this conversion (http://gmod.org/wiki/GFF3<https://urldefense.proofpoint.com/v2/url?u=http-3A__gmod.org_wiki_GFF3&d=DwMFaQ&c=8hUWFZcy2Z-Za5rBPlktOQ&r=fbHa8Njtvh9VmSnzJxiEUTW9NWDwMMwQAzhgZDO41GQ&m=OMPcIr8gCZc0MtV0NaCwpEmyn1zMeLOzW7v7LAyAcDU&s=B1gZmgsg06xIvtRwdOwnNvYzLU-obgTch1fU0jWhy9w&e=>)

Can you please help me?

Sincerely,
Maya
