 +  <a href=/​reference/​ft_sourcedescriptives><​font color=green>​FT_SOURCEDESCRIPTIVES</​font></​a>​ computes descriptive parameters of the source
 +  analysis results.
 + 
 +  Use as
 +    [source] = ft_sourcedescriptives(cfg,​ source)
 + 
 +  where cfg is a structure with the configuration details and source is the
 +  result from a beamformer source estimation. The configuration can contain
 +    cfg.cohmethod ​       = '​regular',​ '​lambda1',​ '​canonical'​
 +    cfg.powmethod ​       = '​regular',​ '​lambda1',​ '​trace',​ '​none'​
 +    cfg.supmethod ​       = '​chan_dip',​ '​chan',​ '​dip',​ '​none'​ (default)
 +    cfg.projectmom ​      = '​yes'​ or '​no'​ (default = '​no'​)
 +    cfg.eta ​             = '​yes'​ or '​no'​ (default = '​no'​)
 +    cfg.kurtosis ​        = '​yes'​ or '​no'​ (default = '​no'​)
 +    cfg.keeptrials ​      = '​yes'​ or '​no'​ (default = '​no'​)
 +    cfg.keepcsd ​         = '​yes'​ or '​no'​ (default = '​no'​)
 +    cfg.keepnoisecsd ​    = '​yes'​ or '​no'​ (default = '​no'​)
 +    cfg.keepmom ​         = '​yes'​ or '​no'​ (default = '​yes'​)
 +    cfg.keepnoisemom ​    = '​yes'​ or '​no'​ (default = '​yes'​)
 +    cfg.resolutionmatrix = '​yes'​ or '​no'​ (default = '​no'​)
 +    cfg.feedback ​        = '​no',​ '​text'​ (default), '​textbar',​ '​gui'​
 + 
 +  The following option only applies to LCMV single-trial timecourses.
 +    cfg.fixedori ​        = '​within_trials'​ or '​over_trials'​ (default = '​over_trials'​)
 + 
 +  If repeated trials are present that have undergone some sort of
 +  resampling (i.e. jackknife, bootstrap, singletrial or rawtrial), the mean,
 +  variance and standard error of mean will be computed for all source
 +  parameters. This is done after applying the optional transformation
 +  on the power and projected noise.
 + 
 +  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.
