I am trying to open my uploaded paired-end MiSeq reads in Trimmomatic from within Galaxy. The picklist for the field for the second set of reads (R2) lets me choose the relevant data set from my uploaded data, but the field for the first (R1) is non-operable. It doesn't let me enter any information and the picklist dropdown does not seem to work either. It is just populated with a message about there not being any fastq data available. I initially thought it might be a browser issue, but no luck. Nothing. Seems to be blocked, and the problem persists across Chrome, IE and Firefox.
Appreciate any help.
