Hi, I would like to generate a screen with a 4 square colored that flash or change color at a frequency chosen, on a black background I tried with Psychtoolbox, but I can not create it. Can you suggest lines of code that do this? Thanks in advance for the help. Greetings, Danilo.

Create a simple GUI with four blocks for the colors.

If you will be running this program on external hardware (like one of the TDT systems), then you may be able to sample the frequency from the external hardware itself. Doing it purely in MATLAB is not possible unless you have some other signal you are synchronizing it to.
