I just started to analyse my RNA-seq data in Galaxy. I started multiple FastQC jobs but now I wanted to cancel them so I delete them from history but it seemed they were still running as I couldn't change my datatype. Any suggestion?
Permanently delete the datasets. Then wait for them to fully quit out. They will turn grey or red when finished, then the inputs can be manipulated again. The speed of this is dependent on a few factors: if the jobs actually started already or were just queued, the load on the server, etc.
