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

  FT_SPIKETRIGGEREDSPECTRUM computes the Fourier spectrup of the LFP around
  the spikes.
 
  Use as
    [sts] = ft_spiketriggeredspectrum(cfg, data)
 
  The input data should be organised in a structure as obtained from
  the FT_APPENDSPIKE or FT_SPIKE_SPIKE2DATA function. The configuration should be according to
 
    cfg.timwin       = [begin end], time around each spike (default = [-0.1 0.1])
    cfg.foilim       = [begin end], frequency band of interest (default = [0 150])
    cfg.taper        = 'dpss', 'hanning' or many others, see WINDOW (default = 'hanning')
    cfg.tapsmofrq    = number, the amount of spectral smoothing through
                       multi-tapering. Note that 4 Hz smoothing means
                       plus-minus 4 Hz, i.e. a 8 Hz smoothing box.
                       Note: multitapering rotates phases (no problem for consistency)
    cfg.spikechannel = string, name of single spike channel to trigger on
    cfg.channel      = Nx1 cell-array with selection of channels (default = 'all'),
                       see FT_CHANNELSELECTION for details
    cfg.feedback     = 'no', 'text', 'textbar', 'gui' (default = 'no')
 
  If the triggered spike leads a spike in another channel, then the angle
  of the Fourier spectrum of that other channel will be negative. NOTE that
  this should be checked for consistency.
