You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: ft_datatype_raw.m
    path of file: ./repos/malini/Codes/deconvolution - model/spm8/external/fieldtrip/fileio/private
    
    the code of the file until where you have to start completion: function data = ft_datatype_raw(data, varargin)


    
function data = ft_datatype_raw(data, varargin)

% FT_DATATYPE_RAW describes the FieldTrip MATLAB structure for raw data
%
% The raw datatype represents sensor-level time-domain data typically
% obtained after calling FT_DEFINETRIAL and FT_PREPROCESSING. It contains
% one or multiple segments of data, each represented as Nchan X Ntime
% arrays.
%
% An example of a raw data structure with 151 MEG channels is
%
%          label: {151x1 cell}      the channel labels (e.g. 'MRC13')
%           time: {1x266 cell}      the timeaxis [1*Ntime double] per trial
%          trial: {1x266 cell}      the numeric data [151*Ntime double] per trial
%     sampleinfo: [266x2 double]    the begin and end
