I am attempting to run a variant call on Gatk. I used the "Validate Variants" tab first, however the reference genome list is not appearing. Shouldn't the reference file, hg19 be embedded in the software already or must I download it?

It was embedded already as a reference file when I ran the variant call in Samtools.


Thanks for any help

The reference genome available natively on the public Main Galaxy instance at is the human version from 1000 Genomes released with the GATK source kit: hg_g1k_b37

Use this for all steps in the analysis process. Mixing genomes will be problematic.

While these tools do permit the use of a Custom reference genome, it works best with smaller ones on Main (memory problems can come up otherwise). If you must use UCSC's hg19, then a production local or cloud Galaxy is best.

Hello Jen,

I'm facing the same problem, I can't use the reference genome even tough I have imported the right .fasta file into my history. I don't know what to do, it just says "No fasta dataset available", please guide me.
