Use gunzip to decompress these downloads, ie.:
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. MRIcron is a good option (use MRIcron, not MRIcro, because you will want nifti support).
Sample input before and after defacing:
