FieldTrip

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

  FT_DATATYPE_STS describes the FieldTrip MATLAB structure for
  spiketriggered spectrum data
 
  Spike triggered spectrum data is characterised as a sparse point-process, i.e. each neuronal
  firing is only represented as the time at which the firing happened.
  For every spike there is a phase value for every (chan x freq)
  combination
 
  sts data is obtained from FT_SPIKE_TRIGGEREDSPECTRUM or
  FT_SPIKETRIGGEREDSPECTRUM
 
  An example sts data structure is:
 
          label: {'lfpchan1'  'lfpchan2'}                                     the channel labels
          time: {[50481x1 double] [50562x1 double] [50537x1 double]}          the time in the trial for each spike (in seconds)
          trial: {[50481x1 double] [50562x1 double] [50537x1 double]}         the trial in which each spike was observed
          trialtime: [100x2 double]                                           the begin- and end-time of each trial (in seconds)
          spikechannel: {'unit1', 'unit2', 'unit3'};                          the labels of the single units        
          fourierspctrm: {[50481x2x20],[50562x2x20],[50537x2x20]};            the fourier spectra for every spike          
          freq: [1x20 double];                                                the vector of frequencies
          cfg: [1x1 struct]                                                   the configuration used by the function that generated this data structure
 
  Required fields:
    - label, trial, time, trialtime, fourierspctrm, spikechannel, freq
 
  Optional fields:
    - hdr, cfg
 
  Deprecated fields:
    - origtrial, origtime
 
  Revision history:
 
  (2011/latest) Made the sts structure similar to the spike structure
 
  (2008): introduced the sts format
