Hi Nina,
I haven't been involved in the bioconda version of jaffa (it's very cool by the way that someone has written a recipe for it!), but it looks like the bioconda version doesn't take the settings:
In the line below in the recipe, the setting would have been passed as a variable between "run" and the groovy pipeline file.
bpipe run $TMPDIR/JAFFA_$RUNMODE.groovy $*
I'll forward to the bioconda author for comment.
Cheers,
Nadia.
