Resting State Functional MRI

Data

See Resting State Task for rest “task” descriptions (projector off, eyes open)

Then sorted by BIDS

Pre-processing

Preprocessing addresses MR Motion (registration), slice timing, fieldmap unwarping (susceptibility correction) skull stripping (brain extraction) for warping (spatial normalization).

A common solution is fmriprep on top of BIDS.

For Habit (as of 2/10/25): 

    /Volumes/Hera/Projects/Habit/mr/fmriprep_habitstudy.bash      nipreps/fmriprep:22.0.0

see fmriprep website to determine specific settings for script and multi-echo processing- https://fmriprep.org/en/stable/workflows.html#:~:text=if%20multi-echo%20bold%20data%20is%20supplied%2C%20this%20workflow%20uses
