 +=====  FT_NETWORKANALYSIS =====

 +<​html><​pre>​
 +  <a href=/​reference/​ft_networkanalysis><​font color=green>​FT_NETWORKANALYSIS</​font></​a>​ computes various network graph measures from
 +  between-channel or between source-level EEG/MEG signals. This function
 +  acts as a wrapper aroun the network metrics implemented in the brain
 +  connectivity toolbox developed by Olaf Sporns and colleagues.
 + 
 +  Use as
 +    stat = ft_networkanalysis(cfg,​ data)
 + 
 +  where the first input argument is a configuration structure (see below)
 +  and the second argument is the output of <a href=/​reference/​ft_connectivityanalysis><​font color=green>​FT_CONNECTIVITYANALYSIS</​font></​a>​.
 + 
 +  At present the input data should be channel-level data with dimord
 +  '​chan_chan(_freq)(_time)'​ or source data with dimord
 +  '​pos_pos(_freq)(_time)'​.
 + 
 +  The configuration structure has to contain
 +    cfg.method ​   = string, specifying the graph measure that will be
 +                    computed. See below for the list of supported measures.
 +    cfg.parameter = string specifying the bivariate parameter in the data
 +                    for which the graph measure will be computed.
 + 
 +  Supported methods are
 +    assortativity
 +    betweenness, ​     betweenness centrality (nodes)
 +    charpath, ​        ​characteristic path length, needs distance matrix as
 +                      input
 +    clustering_coef, ​ clustering coefficient
 +    degrees
 +    density
 +    distance
 +    edge_betweenness,​ betweenness centrality (edges)
 +    transitivity
 + 
 +  To facilitate data-handling and distributed computing you can use
 +    cfg.inputfile ​  ​= ​ ...
 +  cfg.outputfile ​ =  ...
 +  If you specify one of these (or both) the input data will be read from a
 +  *.mat file on disk and/or the output data will be written to a *.mat
 +  file. These mat files should contain only a single variable,
 +  corresponding with the input/​output structure.
