mri_convert atlas.gca -nth 1 labels.mgz
mri_convert atlas.gca -nth 2 priors.mgzwhere:means --> the mean intensity of
the most likely labellabels --> indices of the most likely label at each voxel
(indices refer to '#No.' column of
$FREESURFER_HOME/FreeSurferColorLUT.txt)priors --> the probability that that
label occurs at that voxel
Is it possible to go the other way? I want to create the labels.mgz file and
the others manually, and turn that into the .gca file with mri_convert.
Can this be done?
Thank you,
