FieldTrip

Note that this reference documentation is identical to the help that is displayed in Matlab when you type “help ft_sourcedepth”.

  FT_SOURCEDEPTH computes the distance from the source to the surface of
  the source compartment (usually the brain).
 
  Use as
    depth = ft_sourcedepth(pos, vol);
  where
    pos     Nx3 matrix with the position of N sources
    vol     structure describing volume condition model
 
  A negative depth indicates that the source is inside the source
  compartment, positive indicates outside.
