Hi:

  I completed the co-registration of CT images to a freesurfer processed MRI image using the command:

mri_coreg --mov sub-OAS30001_sess-d3132_CT.nii.gz --reg reg.lta --s OAS30001_MR_d0757

  How can I get the mean and SD Hounsfield units (from corregistered sub-OAS30001_sess-d3132_CT.nii.gz) using aseg.mgz labels (of freesurfered OAS30001_MR_d0757) ?

  Sincerely,
