| Example: | Use gunzip to decompress these downloads, ie.: |
| Line 12: | Line 22: |
| mri_deface orig.mgz talairach_mixed_with_skull.gca face.gca orig_defaced.mgz | mv mri_deface_linux mri_deface chmod a+x mri_deface gunzip talairach_mixed_with_skull.gca.gz gunzip face.gca.gz |

The command usage is: {{{ ./mri_deface <input> talairach_mixed_with_skull.gca face.gca <output> }}} So as an example, to deface your T1-weighted input file, which can be a dicom or nifti, run: {{{ ./mri_deface T1.nii.gz talairach_mixed_with_skull.gca face.gca T1_defaced.nii.gz }}} You will need a volume viewer to view the resulting defaced file. The freesurfer package includes the 'freeview' viewer, but there are many others capable of reading dicom and nifti volumes. [[http://www.mccauslandcenter.sc.edu/mricro/mricron/|MRIcron]] is a good option (use MRIcron, not MRIcro, because you will want nifti support). Sample input before and after defacing: {{attachment:sample_T1_input.jpg}} {{attachment:sample_T1_input_defaced.jpg}} |
