  FT_DATATYPE_SPIKERAW describes the FieldTrip MATLAB structure for raw spike data
 
  Spike data is characterised as a sparse point-process, i.e. each neuronal
  firing is only represented as the time at which the firing happened.
  Optionally, the spike waveform can also be represented. Using the spike
  waveform, the neuronal firing events can be sorted into their single units.
 
  Spike data is obtained using FT_READ_SPIKE to read it from a Plexon,
  Neuralynx or other animal electrophysiology system file format containing
  spikes.
 
  An example spike data structure is:
 
          label: {'chan1', 'chan2', 'chan3'}                         the channel labels
      timestamp: {[1x993 uint64]  [1x423 uint64]  [1x3424 uint64]}   timestamp in arbitrary units, depends on the acquisition system
       waveform: {[32x993 double] [32x433 double] [32x3424 double]}  spike waveform, here described with 32 samples
            hdr: [1x1 struct]                                        the full header information of the original dataset on disk
 
  Required fields:
    - label, timestamp
 
  Optional fields:
    - waveform, hdr, cfg
 
  Deprecated fields:
    - <unknown>
 
  Obsoleted fields:
    - <unknown>
