while the rest of my experiment seems to run with very precise timing (all durations are specified in number of frames), the static component that I am using as an ISI to preload imaged does seem to cause dropped or added frames quite frequently. I have specified the duration of the static component in terms of number of frames x frame duration and it should definitely be long enough to pre-load all the images (~4 seconds). How do I improve timing of a static component? Could I, for example, wait for the next flip before starting the ISI?
All help is appreciated!
