[galaxy-user] How to lower disc usage in order to resume workflow

Hello, Re: https://usegalaxy.org/u/cmfarnet/h/pf2-34-map-1-r1-only I am a new user, and I uploaded WGS data to perform the published "CloudMap Hawaiian Variant mapping with WGS" workflow (History link above). I received the notice: "You are over your disk quota. Tool execution is on hold until your disk usage drops below your allocated quota." Can you please let me know how I can reduce my disc usage so the the job can continue? Thanks so much for your help! Chris Farnet Dept. of Biology McGill University
