What is the variable for the current frame of the loop?

Hi all,

We want to count the frames during a trial to time our port signals for specific time windows (e.g. fixation, stimulus, padding, iti). I was wondering if there is a variable for calling numerical value of the current frame within “each frame” tab. I saw something like thisN, not sure if that’ll work or not. I would appreciate any help!

Try frameN
