I’m having some trouble processing data on openneuro with fmriprep. The data is multiband data with a TR of 460 ms (wasn’t my choice) and 894 volumes. I have 6 runs and my analysis for a single-subject takes over 48 hrs so the jobs are being killed. Looking at the logs, it appears that melodic took 19 hours for one run:

I’ve run MELODIC on these data before through ICA_AROMA.py and I’m pretty sure they only took a few hours. Is there anything I can do to reduce the duration?
I’ve tried re-running the analysis hoping it would pick up where it left off like fmriprep will do with docker, but it doesn’t appear that this is the case.
Thanks,
Joe
