 https://github.com/HarveyLab/mouseVR/blob/master/Software/Virmen/transformations/fliptransformCyl_NPparab.m Is an example of a ViRMEn transformation function that works reasonably well with this setup. It isn't the most accurate but looks fairly good to me and I've had good mouse behavior. Some people have approximated the parabola as a cylinder which can speed things up. If you're doing something that requires knowing exactly where in the visual field something is presented, don't rely on this function.

 # Headfixation
 
 Head-fixation harware is somewhat is independent of the VR setup, but here are some designs for headplates and headplate holders developed in the Harvey lab for our experiments.
