Task-functional brain images in NIFTI format.
The source DICOM images were acquired using the following parameters:
Resolution: 2.4x2.4x2.4 mm
Field-of-view: 88x88x64 matrix
Duration: 4 minutes (332 timepoints)
TR: 0.735 s
TE: 39ms
GE-EPI with x8 multislice acceleration, no iPAT, flip angle 52 degrees, fat saturation
As implemented in the CMRR multiband acquisition, a separate "single-band reference scan" is also acquired. This has the same geometry (including EPI distortion) as the timeseries data, but has higher between-tissue contrast to noise, and is used as the reference scan in head motion correction and alignment to other modalities.
The average size of these NIFTI datasets is 450MB per participant.
