| For your own data, substitute the name of your T1-weighted input file, which can be a dicom or nifti: {{{ ./mri_deface my_T1.nii talairach_mixed_with_skull.gca face.gca my_T1_defaced.nii }}} 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. {{attachment:sample_T1_input.jpg}} {{attachment:sample_T1_input_defaced.jpg}} |

Use gunzip to decompress these downloads, ie.:
gunzip mri_deface-v1.22-Linux64.gz cp mri_deface-v1.22-Linux64.gz mri_deface chmod a+x mri_deface gunzip talairach_mixed_with_skull.gca.gz gunzip face.gca.gz
