External Email - Use Caution Hi Bruce,
thank you it worked! Another short question: I want mri_surf2vol to assign the average of all volume voxel values within 10 mm to the corresponding vertices. So if there is only one voxel value greater than zero in the volume, all vertices which are closer than 10 mm should get that value (or the mean if there is more than one value). Can I use ' --projdist 10' for this purpose? Thank you!! Cheers, Michael Am Mo., 18.
