I’m running connectome generation for 54 subjects on a cluster with 48 cores. When I’ve submitted 48 jobs for 48 subjects together, I’ve noticed that steps ‘tckgen’ and ‘tcksift’ took incredibly long time to run. Is there a more efficient way to go about? I’ve read elsewhere that by default these commands use maximum number of threads available. Should I limit that explicitly by the ‘-nthreads’ option?
