I'm running an algorithm on a pair, and (among other things) it generates an output file for both the case and the control samples. But, when I try to assign the output file to self.case_id. I get an error when saving the method config:
Failed at line 1, column 13: :' expected but.' found
Changing the second '.' to ':' gives an even more cryptic error.
How can I make this work?
