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

  FT_ANONIMIZEDATA clears the value of potentially identifying fields in
  the data and in the provenance information, i.e., it updates the data and
  the configuration structure and history that is maintained by FieldTrip
  in the cfg field.
 
  Use as
    output = ft_anonimizedata(cfg, data)
  where data is any FieldTrip data structure and cfg is a configuration
  structure that should contain
    cfg.keepnumeric = 'yes' or 'no', keep numeric fields (default = 'yes')
    cfg.keepfield   = cell-array with strings, fields to keep (default = {})
    cfg.removefield = cell-array with strings, fields to remove (default = {})
    cfg.keepvalue   = cell-array with strings, values to keep (default = {})
    cfg.removevalue = cell-array with strings, values to remove (default = {})
 
  The graphical user interface consists of a table that shows the name and
  value of each provenance element, and whether it should be kept or
  removed. Furthermore, it has a number of buttons:
    - sort        specify which column is used for sorting
    - apply       apply the current selection of "keep" and "remove" and hide the corresponding rows
    - keep all    toggle all visibe rows to "keep"
    - remove all  toggle all visibe rows to "keep"
    - clear all   clear all visibe rows, i.e. neither "keep" nor "remove"
    - quit        apply the current selection of "keep" and "remove" and exit
 
  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.
