yep, exactly

Hi Doug, After I have the labels then in each subject's T1 space, I will need to then put them into diffusion and resting state space.
I already have scripts that put the parcellations into subject-specific diffusion/resting state space (using bbregister, tkregister2, mri_vol2vol (using the inverse registration from bbregister to put the T1 into diffusion space), mri_extract_label (extract labels from aparc+aseg.mgz), and then mri_label2vol (register each of the extracted labels into diffusion space). Would a similar approach work for the new labels?

Exactly what you have described won't work very well because it would be in the volume. I would divide up the parcellations in fsaverage space like you've done, then map the parcellation to each subject using mri_surf2surf (--sval-annot, see example 6) doug On 04/08/2014 04:54 PM, Corinna Bauer wrote: > Hello all, > > I am planning to use mris_divide_parcellation to split the Desikan > atlas into smaller ROIs, but will need the new ROIs to be consistent > between subjects. > > Can I achieve this if I register each subject to fsaverage space and > then apply the inverse transform to the divided parcellations (which > are currently done on the fsaverage brain)? > > If so, for extracting each label, what would be used for the label > number? > (i.e. mri_extract_label ${subj_dir}/mri/aparc+aseg.mgz *2035* > ${subj_dir}/hardi_labels/ctx-rh-insula.nii) > > > Thanks > > Corinna > > > _______________________________________________ > Freesurfer mailing list > Freesurfer@nmr.mgh.harvard.edu <mailto:Freesurfer@nmr.mgh.harvard.edu> > https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer -- Douglas N.
