This directory contains several demonstration scripts for the Vision Egg library. Most of these demos are merely a feature overview of the Vision Egg, are not meant to be used for experiments. You can rename the files from *.py to *.pyw so they don't open a console window. On Mac OS X this may be required (depending on how Python is configured). The multi_stim.py demo shows many stimuli at once, and may be a good starting point. The metaPyroServer.py and metaPyroGUI.py scripts are the easiest place to get started creating a complete experiment generation application using a pure Python approach. These demos are advanced and attempt to "put it all together". The ephys_server.py and ephys_gui.py applications one step farther. Another example of a script that could be used for experiments is the gratingTCP script in the tcp directory. This can be controlled by gratingGUI, the LabView VIs contributed by Jamie Theobald, or your own program. See trigger_out in the daq directory to see how you could combine it with triggering for easy integration into your current data acquisition system.
