python for psychophysical test

[eagle112800]

Vizar works great and the lab I am in uses it all of the time, but we are going to do an experement which requrers very acuret time stamping and of less then a milisecond.
I need to either find a way to make the VR see through headset load and run from matlab, or a way to create a meternome accuret to the milisicend and then record the keyboard imput with a time stamp and be able to make histograms matching the inital point of the key press with the closest time to the sound (this is much harder since I have the code written in matlab already). I need to also insert a delay in the headset at spific points and the intersence cube is not needed for this experement. Another optionwhich may be the easiest is to interface matlab and vizard, but I am not complytly sure how to do tell the programs what to do.

Thanks,

Gregory
