Timing in seconds or frames

Hi There,

It is most accurate to time in terms of frames, what you could do is use the variable expInfo['frameRate'] to calculate how many frames you need for your desired time - that variable will give you the frameRate of the individual set up so it should translate across devices.

For example, if I wanted to present something for 50ms (or as close to as pos) across devices I could say

presentationFrames = int(50 / (1000/expInfo['frames']))

then use the variable presentationFrames in the duration field of your stimulus.

Hope that helps,
Becca
