Hi,  
  
Does anyone know how I can capture the screen image and save it as a  
jpeg? I have a code that generates videos using the toolbox but I  
would like to save each presented frame as a jpg or bitmap image.  
  
Thanks,  
  
Aaron

Hello,  
Dear Aaron  
  
You can use the following psychtoolbox function to capture the screen  
  
imageArray=Screen('GetImage', windowPtr [,rect] [,bufferName] [,floatprecision=0] [,nrchannels=3])  
  
and then, you can use MATLAB function "imwrite" to save your image, imageArray.  
  
Have a good time,  
Amir
