What is the easiest way to setup/program a spatial nAFC stimuli? Use the multi-elements field in some way? The tutorials are pretty clear on a temporal 2AFC task, but I'm not clear on setting up a spatial one.

Designing a spatial nAFC task is actually very similar to designing a temporal nIFC task: there is Spatial/Temporal options under the nFC procedure tab. Have a look at the "Procedure" section of the on-line documentation:

You may also check out the "4-spatial-AFC" experiment for measuring RDK coherence threshold found in "Demo, Examples & Tutorial --> Experiments --> RDK --> Coherence Threshold" under the "Storage" section of the Designer panel.

Hope this helps!
