[visionegg] Re: counting frames

Ah, so what is defined in temporal_variables is what get passed to text_func?. Does one just pass a list? Also, is this true for other functions in the function controller? Can I get these values out of the presentation object?

Hi,
I've been looking through the samples... it appears from the demos that I can have tasks execute based on a time (t) variable passed but there are these f_fabs variables I would much prefer to use. I need to count frames and have stimuli presented on them. Its a simple TOJ task and an RSVP task I want to use. Do I actually have to just present an image on every frame and then time until what I believe is close to the number of frames? 

Hi John,
I don't know what TOJ and RSVP tasks are, but I think I can answer anyway. I just added a new demo: http://visionegg.org/trac/browser/ trunk/visionegg/demo/framecount.py 

Does that help?
