Beautiful - don't how I missed it.  Thank you.
Getting the hang of this thing.

Hi MNErs.

I'm rather new to MNE, and am used to working with brainvision instead.

I can not figure out to create a new event based on whether other specific events are in a specifed

Proximity (is there a function to do this?). I see there is merge events but this does not seem to

provide what I need.



To explain, I have loads of stimulus locked triggers which are sent by a light stimulus so are perfect fortiming - this Is what I want to timelock my ERPs to. However, the light stimulus is always called the same event, e.g., 'lightsensor'.

In Brainvision, I would create my segments based on the subsequent triggers/events, as they tell me what stimulus the light sensor relates to.



e.g., on every trial, I have  'Lightsensor' followed within 100ms by either 'Negative' or "neutral'.



How do I create an event so that the lightsensor is can be coded as 'Negative' and 'Neutral' when appropriate?



Thank you!
