[Eeglablist] Events not listed when extracting epochs with pop_epoch

[Becky Prince]

Dear EEGLAB users,

I'm trying to create epochs around a set of events in my data.  The event
markers are all numbers (1 and 50:89).  When I go to Tools -> Extract
Epochs, then click the '...' in the 'Time-locking event type(s)' row to
select from the events in my data, only two event types (1 and 50) appear
in the event types browser box.  I know that I have more event types
because I've checked EEG.event.type and Edit -> Event values.

For example, here is an event marked '55':
 >> EEG.event(9)
 ans =
        type: '55  '
        latency: 10726
        duration: 0

To extract the epochs around the events 50:89, I've tried scripting this:
  EEG = pop_epoch( EEG, {  '50' '51' '52' '53' '54' '55' '56' '57' '58'
'59'...
    '60' '61' '62' '63' '64' '65' '66' '67' '68' '69'...
    '70' '71' '72' '73' '74' '75' '76' '77' '78' '79'...
    '80' '81' '82' '83' '84' '85' '86' '87' '88' '89'  },...
    [-0.2  0.5], 'newname', '4_1_vad_ep', 'epochinfo', 'yes');

But this produces an error (regardless of whether the event values are
space-separated or comma-separated):
  ??? Error using ==> pop_epoch at 229
  pop_epoch(): empty epoch range (no epochs were found).

I also get the above error when trying to epoch a single event value.  Does
anyone know why the epoch extraction isn't working?  Did I miss a step
somewhere, like editing the event fields or values?  I'd be very grateful
for any advice!

Thanks,
Becky
