Check that box and enter a paint column name (or select existing column).
But I'm confused how you are doing this with subcortical regions. Do you have subcortical surfaces? I'm used to subcortical regions being dealt with volumetrically, rather than as surfaces, since those structures are more like nuclei than a sheet (like the cortex). If you somehow do have a subcortical surface, it is possible to project the surface to a sheet of voxels and then do Volume: Segmentation: Fill Cavities to fill it. Then save the resulting volume. I probably am misunderstanding what you want to do. > Thank you for your help. > > Michelle > > > > _______________________________________________ > caret-users mailing list > [email protected] > http://brainvis.wustl.edu/mailman/listinfo/caret-users > _______________________________________________ caret-users mailing list [email protected] http://brainvis.wustl.edu/mailman/listinfo/caret-users
