How to trigger analog inputs on a threshold levels using session based interface?

Hello,

I am using Matlab 64 bits for data acquisition using NI instruments. I am acquiring the signal from an analog input. I would like to trigger the acquisition when that signal reaches a certain threshold. I am not able to find any help on that using session-based interface (the only help is about using digital triggers). I know it was possible using legacy commands, but I am not sure how to adapt it to session-based commands.

Thank you for your help

I am also looking for a solution. This is not hard with legacy interface, but we are now forced into the session based interface.
