Note that this reference documentation is identical to the help that is displayed in MATLAB when you type “help loreta2fieldtrip”.

  LORETA2FIELDTRIP reads and converts a LORETA source reconstruction into a
  FieldTrip data structure, which subsequently can be used for statistical
  analysis or other analysis methods implemented in Fieldtrip.
 
  Use as
    [source]  =  loreta2fieldtrip(filename, ...)
  where optional arguments can be passed as key-value pairs.
 
  filename can be the binary file from LORETA or a LORETA file exported as
  a text file (using the format converter in LORETA-KEY).
 
  The following optional arguments are supported
    'timeframe'  =  integer number, which timepoint to read (default is to read all)
