The FreeSurfer Maintenance Dataset This data was collected as part of the FreeSurfer Maintenance grant (FSM; R01EB023281) to support development and testing of FreeSurfer. The dataset contains the following scans: - Anatomical - 12-echo gradient echo (GRE); magnitude and phase - MP2RAGE; both inversion contrasts, T1 map and uniform image - 4-echo MPRAGE with volumetric navigators (vNavs); magnitude, phase and RMS - T2-SPACE with volumetric navigators (vNavs) - Diffusion - Multi-shell diffusion data - Functional - 50-repetition resting state data - Field Map - GRE phase-difference field maps - EPI blip-reversed field maps Notes: - All anatomical data was defaced with mideface (surfer.nmr.mgh.harvard.edu/fswiki/MiDeFace) - More details on how the dataset was curated is available at github.com/pwighton/fsm2bids/
