Once you are finished editing, save the changes to the volume with File – Save Aux volume. Then, cd into the mri directory of this cross data set, and make a copy of the edited brain.finalsurfs.mgz file to one called brain.finalsurfs.manedit.mgz.: EXAMPLE FOR MR1: 1. cd OAS2_0002_MR1/mri 2. cp brain.finalsurfs.mgz brain.finalsurfs.manedit.mgz |
