[Eeglablist] concatenate .set files

[Julie Onton]

Hi Darren,

Yes, there is an EEGLAB function to do just that. Under Edit->Append datasets, list the current
datasets to merge. It will check for consistency across datasets. The function from the
commandline is called 'pop_mergeset':

help pop_mergeset
  pop_mergeset() - Merge two or more datasets. If only one argument is given,
                   a window pops up to ask for more arguments.
  Usage:
    >> OUTEEG = pop_mergeset( ALLEEG ); % use a pop-up window
    >> OUTEEG = pop_mergeset( ALLEEG, indices, keepall);
    >> OUTEEG = pop_mergeset( INEEG1, INEEG2, keepall);

  Inputs:
   INEEG1  - first input dataset
   INEEG2  - second input dataset

  else
   ALLEEG  - array of EEG dataset structures
   indices - indices of EEG datasets to merge

   keepall - [0|1] 0 -> remove, or 1 -> preserve, ICA activations
             of the first dataset and recompute the activations
             of the merged data {default: 0}

  Outputs:
   OUTEEG  - merged dataset
