Hello,
We are using 14 Bpods (r1), controlled with python (PyBpod).
In each Bpod, we use 3 ports, the left and the right supply water and the central one simply detects the position of the animal with the photogate (it does not use the valve to deliver water).
We have a problem that happens randomly on 3 of the Bpods. Occasionally there are bursts of detections on the central port photogate (thousands of in and out detections per second) for a few seconds and then everything goes back to normal.
We changed the position of the problematic ports (we are only using 3 of the 8 possible behavioral ports on each bpod, so we had 5 free) and then restarted the Bpods.
The issue was resolved for a few days, but now it seems to be happening again on one of the Bpods.
What could be the reason for these overdetections? We thought it would be a problem in the port's photodetector, but we were surprised that it stopped happening by changing their position and restarting the Bpods.
