Nothing is working at all.
Is it the same error? if it not too much trouble, you can try to use a Cygwin terminal, which acts more like a Linux shell, which I am better at navigating. The code on the fMRIPrep website often uses Linux-like syntax, so it’s easier to borrow their documentation. Also, maybe the “\” symbols in the command we have works different in windows than in Linux. The “\” usually works as a line break in Linux, but is used for indexing directories in windows, which might also cause errors.
