[galaxy-dev] Setting up reference genomes for GATK Genotyper

Hi, I am running an instance of Galaxy that I setup using Cloudman. We are trying to use the GATK Unified Genotyper, but we are missing the reference genomes. I saw in your website instructions on how to setup reference genomes for some other tools, but not for the Unified Genotyper. Where can I find instructions on how to setup reference genomes for this tool? Thanks Marco
