[Eeglablist] How to disentangle two events?

Dear EEGLAB experts,

does anyone know a way/script with which I can delete one event if it is too close to another event (so like if “event 1” <10ms away from “event 2” then erase)?

In my experiment, I use photodiodes to send triggers. If one is active alone, this is one event (“1”/”3”), if two are active, it should be another(“2”). When both diodes are activates however, occationally I get first the one and then the other event, as if my monitor ist too slow to present light for both triggers at the same time. 

In the EEG-data, this results in the two events beeing at the (almost) exact same time (i.e. “1”and”2”) so that I have to erase the one event by hand from the data. As this happens around 100 times per experiment I was wondering if this could be done automatically. 

I am sorry if this is a trivial question for advanced users, I have only started using EEGlab recently. 

Thank you so much for your help!
