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

  FT_SELECTDATA serves to subselect regions-of-interest from the input data,
  with or without averaging across the specified dimensions. It also
  concatenates multiple input data structures along the compatible
  dimension and is thus a more general implementation of ft_appenddata,
  which deals only with raw data.
 
  Use as
   [data] = ft_selectdata(data1, data2, ..., key1, value1, key2, value2, ...)
 
  Supported input data:
    freq
    timelock
    source
    volume   (not yet)
    raw      only for subselection of channels and replicates. this is the
               same functionality as ft_preprocessing
 
  Optional input arguments should be specified as key-value pairs and may include
    param         string
    foilim        [begin end]  edges of frequency band to be retained
    toilim        [begin end]  edges of time window to be retained
    roi           [Nx1]        indices of voxels of region-of-interest
    rpt           [Nx1]        indices of replicates to be retained
    channel       {Nx1}        list of channels labels to be retained
    avgoverchan   'no' ('yes') average across channels
    avgoverfreq   'no' ('yes') average across frequency bins
    avgovertime   'no' ('yes') average across time points
    avgoverroi    'no' ('yes') average across voxels in ROI
    avgoverrpt    'no' ('yes') average across replicates
