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

  FT_FETCH_EVENT mimics the behaviour of FT_READ_EVENT, but for a FieldTrip
  raw data structure instead of a file on disk.
 
  Use as
    event = ft_fetch_event(data)
 
  See also FT_READ_EVENT, FT_FETCH_HEADER, FT_FETCH_DATA
