Hi,

I created visual stimuli with psychtoolbox. I would like to create the stimuli info into matrix in Matlab. is there any function that can save the stimuli as matrix in Matlab?  
Thank you.

Screen(‘GetImage’ should do the trick

Hi dcnieho,

My stimuli are moving so GetImage can give only static image I think. Is there a way to save the stimuli into matrice like in movie format?

Thanks.

Look at the movie writing code in ImagingStereoDemo.m for that.
