 +  <a href=/​reference/​ft_defacevolume><​font color=green>​FT_DEFACEVOLUME</​font></​a>​ allows you to de-identify an anatomical MRI by erasing specific
 +  regions, such as the face and ears. The graphical user interface allows you to
 +  position a box over the anatomical data inside which all anatomical voxel values will
 +  be replaced by zero. You might have to call this function multiple times when both
 +  face and ears need to be removed. Following defacing, you should check the result
 +  with <a href=/​reference/​ft_sourceplot><​font color=green>​FT_SOURCEPLOT</​font></​a>​.
 + 
 +  Use as
 +    mri = ft_defacevolume(cfg,​ mri)
 + 
 +  The configuration can contain the following options
 +    cfg.translate ​ = initial position of the center of the box (default = [0 0 0])
 +    cfg.scale ​     = initial size of the box along each dimension (default is automatic)
 +    cfg.translate ​ = initial rotation of the box (default = [0 0 0])
 +    cfg.selection ​ = which voxels to keep, can be '​inside'​ or '​outside'​ (default = '​outside'​)
 +    cfg.smooth ​    = '​no'​ or the FWHM of the gaussian kernel in voxels (default = '​no'​)
 +    cfg.keepbrain ​ = '​no'​ or '​yes',​ segment and retain the brain (default = '​no'​)
 +    cfg.feedback ​  = '​no'​ or '​yes',​ whether to provide graphical feedback (default = '​no'​)
 + 
 +  If you specify no smoothing, the selected area will be zero-masked. If you
 +  specify a certain amount of smoothing (in voxels FWHM), the selected area will
 +  be replaced by a smoothed version of the data.
