[Eeglablist] Crop EEG segments in command line

[Stephen Politzer-Ahles]

Hi Carlos,

I'm not sure about your exact situation, but if want to define conditions
using multiple markers, I think ERPLAB (a plugin for EEGLAB) offers more
options for defining conditions; if you have trouble getting what you need
using pop_select, you might try out ERPLAB.

Best,
Steve Politzer-Ahles
