[Eeglablist] code for converting EEGLAB to fieldtrip data formats (and vice versa)

Wambua, something like this should convert segmented events in EEGLAB .set
files to FieldTrip structures. Not sure how to go back to EEGLAB. Hope it
helps.

% ========================================
eventVales = {'target','lure'};

% the amount of time before and after the segmented events, in seconds
prepost = [0.5 1.5];

% importing eeglab .set files
ftype = 'eeglab_set';

% initialize the data structure
data = struct;

% add each event value as a field in the data struct
for evVal = 1:length(eventValues)

  % path to the eeglab .set file
  infile = fullfile('path/to/files',[eventValues{evVal},'.set']);

  cfg = [];
  cfg.dataset = infile;
  cfg.headerfile = infile;
  cfg.dataformat = ftype;
  cfg.headerformat = ftype;
  cfg.continuous = 'no';

  cfg.trialdef.prestim = prepost(1);
  cfg.trialdef.poststim = prepost(2);
  cfg.trialfun = 'trialfun_general';
  cfg.trialdef.eventtype = 'trigger';
  cfg.trialdef.eventvalue = eventValues{evVal};
  cfg = ft_definetrial(cfg);

  data.(eventValues{evVal}) = ft_preprocessing(cfg);
end
