FieldTrip

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

  FT_DIPOLESIMULATION computes the field or potential of a simulated dipole
  and returns a datastructure identical to the FT_PREPROCESSING function.
 
  Use as
    data = ft_dipolesimulation(cfg)
 
  You should specify the volume conductor model as defined by FT_FETCH_VOL
  If the sensor information is not contained in the data itself you should
  also specify the sensor information, see FT_FETCH_SENS
 
  optionally
    cfg.channel    = Nx1 cell-array with selection of channels (default = 'all'),
                     see FT_CHANNELSELECTION for details
 
  The dipoles position and orientation have to be specified with
    cfg.dip.pos     = [Rx Ry Rz] (size Nx3)
    cfg.dip.mom     = [Qx Qy Qz] (size 3xN)
 
  The timecourse of the dipole activity is given as a single vector or as a
  cell-array with one vectors per trial
    cfg.dip.signal
  or by specifying a sine-wave signal
    cfg.dip.frequency    in Hz
    cfg.dip.phase        in radians
    cfg.dip.amplitude    per dipole
    cfg.ntrials          number of trials
    cfg.triallength      time in seconds
    cfg.fsample          sampling frequency in Hz
 
  Random white noise can be added to the data in each trial, either by
  specifying an absolute or a relative noise level
    cfg.relnoise    = add noise with level relative to simulated signal
    cfg.absnoise    = add noise with absolute level
