This has nothing to do with the contrast. Try the suggestion that was printed out at the end (ie, remove the mean from the age and divide by the stddev) On 06/04/2018 09:28 AM, C.P.E. Rollins wrote: > External Email - Use Caution > Dear Freesurfer developpers, > > I posted a while back asking h

-parc_dir should really be "seg volume". It is the name in the mri dir of the volume that contains the manual labelings. xform we use to put it in Tal coords. We also usually iterate where we build an initial atlas, then align all the volumes to it and rebuild, but if you have talairach.m3z yo

Hi Arselle the node_spacing is the mm resolution of the atlas Markov priors and class-conditional densities, the prior_spacing is the same for the classwise spatial priors the equivalent for the surface is mris_ca_train. It takes annot files as input cheers Bruce On Mon, 4 Jun 2018, arsen
