Gait Measurement EMG Step Trigger

Script for Spike2 software to control stimulus delivery using input from an external signal. This script was developed and used in the laboratory of Veronique VanderHorst, MD PhD at Beth Israel Deaconess/Harvard Medical School. Specifically, this script was used to trigger pulses of light that were delivered to animals receiving optogenetic stimulation; the trigger was designed to detect the initiating of stepping by electromyographic activity that was recorded from the tibialis anterior. This script also activates a physical stopwatch at the initiation of data collection for purpose of synchronizing with video.
