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

  FT_SELECTDATA makes a selection in the input data along specific data
  dimensions, such as channels, time, frequency, trials, etc. It can also
  be used to average the data along each of the specific dimensions.
 
  There exist two implementations with a different calling style, i.e. a
  different specification of the input arguments. Eventually all the
  functionality will be merged again. This present FT_SELECTDATA function
  is a wrapper function that will automatically select between the two.
  Please be aware that the old implementation will be phased out.
 
  Use as
   [data] = ft_selectdata_old(data1, key1, value1, key2, value2, ...)
  or as
   [data] = ft_selectdata_new(cfg, data, ...)
