¥3dfractionize
does this resolution conversion:

-input ROI_high_res+orig -clip 0.5 -preserve -prefix
ROI_low_resH-template func+orig ¨ The destination grid you want your ROI grid
to be
resampled to (weÕre going from high to low resolution here). Our output dataset
ROI_low_res+orig will be
written at the resolution of func+orig

least 50% filled
by nonzero input voxels (you decide the percentage here). E.g., when going
from high to low res, keep a label a voxel as part of the ROI if it is filled with
at least 50% (or more) of the voxel value. For example:
filled
by nonzero input voxels (you decide the percentage here). E.g., when going
from high to low res, keep a label a voxel as part of the ROI if it is filled with
at least 50% (or more) of the voxel value. For example:This voxel is 80% filled
with the ROI value -- keep it
This voxel is 30% filled
with the ROI value -- lose it
