code: def read_raw_fieldtrip(fname, info, data_name="data") -> RawArray:
      """Load continuous (raw) data from a FieldTrip preprocessing structure.
  
      This function expects to find single trial raw data (FT_DATATYPE_RAW) in
      the structure data_name is pointing at.
  
      .. warning:: FieldTrip does not normally store the original information
                   concerning channel location, orientation, type etc. It is
                   therefore **highly recommended** to provide the info field.
                   This can be obtained by reading the original raw data file
                   with MNE functions (without preload). The returned object
                   contains the necessary info field.
  
      Parameters
      ----------
      fname : path-like
          Path and filename of the ``.mat`` file containing the data.
      info : dict or None
          The info dict of the raw data file corresponding to the data to import.
          If this is set to None, limited information is extracted from the
          FieldTrip structure.
      data_name : str
          Name of heading dict/variable name under which the data was originally
          saved in MATLAB.
  
      Returns
      -------
      raw : instance of RawArray
          A Raw Object containing the loaded data.
          See :class:`mne.io.Raw` for documentation of attributes and methods.
