When using spm12's new segmentation, ft_volumesegment returns more than the specified tissues. Test script: -------------------------------------------- mri = ft_read_mri('Subject01.mri'); cfg = []; cfg.dim = mri.dim; mri = ft_volumereslice(cfg,mri); cfg = []; cfg.output = {'gray','white','csf','skull','scalp'}; cfg.spmversion = 'spm12'; cfg.spmmethod = 'new'; segmentedmri = ft_volumesegment(cfg, mri); % segmentedmri contains the desired tissues as binary maps % - but additionally TPMs of bone, softtissue, and air.
