Adding Schaefer2018 MNI nifti image to FSL atlases


I would like to create anatomical ROIs in FSL that are based on the Schaefer2018 parcellation. I have a nifti file and lookup table from their github, but not an xml specification that FSL needs to add atlases.

alternatively, is it possible to create an ROI binary mask from a lookup take? or the nifti image itself?
