Dear Ms. Hillman Jackson,
As a matter of fact, I am using usegalaxy.org server (logged in as admin edit: remove full email for privacy). I executed Unicycler hybrid assembly (jobs 43-46), however, they are pending for a week. I used this tool before at your server, and it worked fine.
I look forward to hearing from you.
It sounds like you are not working at usegalaxy.org and are contacting your admins for the server you are working on to troubleshoot the problem. Hope that works out!
Thanks! Jen, Galaxy team
