I realize Relion now has it's own implementation of motion correction, but for those using the motionCor2 wrapper, I wonder if it would be possible make a minor change which would allow using multiple GPUs from the gui using notation consistent with that used elsewhere in Relion? Specifically, commas are typically used to separate GPUs (e.g, "0,1,2,3") for a single process in the Relion Gui. But this doesn't seem to work correctly for motionCor2 1.2.1. MotionCor2 exepcts GPUs separated by spaces and doesn't seem to accept commas. At least in my hands, it winds up using only a single GPU if commas are entered in the gui. What does seem to work, at least for me is entering the GPUs separated by spaces (e.g. "0 1 2 3", but without the quotations). The difference in speed is considerable obviously.
Thanks for considering this!
