The EXP program software is designed to control biophysical experiments in various specialized environments, such as the Patient Lab, the Robot Arm Lab, and the NIRS/EEG facilities. The code defines an extensive structure of classes and functions for managing hardware, including RZ6 systems, LED controllers, motors, and head movement systems. Additionally, the script incorporates logic for adaptive algorithms, stimulus generation, and the handling of real-time experimental data via various protocols. Detailed specifications for audiological equipment and loudspeakers are integrated directly into the code to ensure accurate calibration.
