I would like to ask a question about trac-preproc, because I'm new to Tracula and I'm studying how the entire trac-all process works. I want to know which is the specific structural image (I mean the name of the file) that is registered to the dwi volume during trac-preproc, and at which point of the process this is done. I'm doing this because I want to track down all the movements of the files used by Tracula. Thanks,
