Gets the cortical mask for a particular transform

Parameters

subjectstr

Subject name

xfmnamestr

Transform name

typestr

Mask type, one of {‘cortical’,’thin’,’thick’, ‘nearest’}. ‘cortical’ is exactly the cortical ribbon, between the freesurfer-estimated white matter and pial surfaces; ‘thin’ is < 2mm away from fiducial surface; ‘thick’ is < 8mm away from fiducial surface. ‘nearest’ is nearest voxel only (??)

Returns

maskarray

boolean mask array for cortical voxels in functional space
