FieldTrip

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

  FT_HEADMOVEMENT creates a representation of the CTF gradiometer definition
  in which the headmovement in incorporated. The result can be used
  for source reconstruction.
 
  Use as
    grad = ft_headmovement(cfg)
  where the configuration should contain
    cfg.dataset      = string with the filename
    cfg.trl          = Nx3 matrix with the trial definition, see FT_DEFINETRIAL
    cfg.numclusters  = number of segments with constant headposition in which to split the data (default = 12)
