 +  <a href=/​reference/​ft_transform_geometry><​font color=green>​FT_TRANSFORM_GEOMETRY</​font></​a>​ applies a homogeneous coordinate transformation to a
 +  structure with geometric information,​ for example a volume conduction model for the
 +  head, gradiometer of electrode structure containing EEG or MEG sensor positions and
 +  MEG coil orientations,​ a head shape or a source model.
 + 
 +  The units in which the transformation matrix is expressed are assumed to be the
 +  same units as the units in which the geometric object is expressed. Depending on
 +  the input object, the homogeneous transformation matrix should be limited to a
 +  rigid-body translation plus rotation (MEG-gradiometer array), or to a rigid-body
 +  translation plus rotation plus a global rescaling (volume conductor geometry).
 + 
 +  Use as
 +    output = ft_transform_geometry(transform,​ input)
 +  where transform should be a 4x4 homogenous transformation matrix and the input data
 +  structure can be any of the FieldTrip data structures that describes geometrical
 +  data.
