Parameter "out_dir" is not used

[tsalo]

out_dir is an argument in the parser and in the main workflow function, but it's never actually used. The easiest solution might be to drop it completely.

Yeah, it predates the switch to all BIDS all the time and I kept it around just in case I ended up needing it later. I think you're right, though. I'll put it on my list.
