[Eeglablist] Error in pop_epoch command line

[Arnaud Delorme]

Dear Kelly,

I notice that your events are followed by space characters. That could be the issue. It could also be that your events are numbers not strings. Try without the extra space character

EEG = pop_epoch( EEG,  { ‘510' ’511' '610'  '611'  '710'  '711'  '810'  '811'  }, [-2  2], 'newname', 'EGI file resampled pruned with ICA epochs', 'epochinfo', 'yes’);

or try using numerical events

EEG = pop_epoch( EEG,  [ 510 511 610 611 710 711 810 811 ], [-2  2], 'newname', 'EGI file resampled pruned with ICA epochs', 'epochinfo', 'yes’);

If it still does not work, to see your event types, type on the command line

eeg_eventtypes(EEG)

Best wishes,

Arno

I don't understand what the issue is. Can anyone help? Since I'm processing so many sets through a long pipeline, loading each one into the GUI to epoch will significantly slow down what would otherwise be an automatic process.
