Test the nasal cannula, compare signal with breathing belt

[Fehings]

Summary

We have shown that we can read and parse the breathing belt signal, need to do the same with the nasal monitor and make sure that we don't need any extra steps. Would also be good to show that we can read the signal and calibrate it with the GUI.

What needs to be done?

• [x] Set up and test the nasal cannula, including hooking the signal through the ad instruments and NIDAQ.
• [x] Check the signal is being read by the ad instruments board
• [x] Check the signal is being read through the NIDAQ and GUI
• [x] Try and have concurrent with breathing belt (do we have enough cables?)
• [x] Compare with breathing belt signal for cleanness, can we get a breathing locked stimulation?
• [x] Document the comparative results and any extra steps needed.

NB: ideally we want both the breathing belt and the nasal cannulae, and we want to be able to switch between the two inputs in the GUI

No extra steps needed, hooking up with input direct to ad instruments and DINout to NIDAQ, this is being read from both nidaq and ad instruments nice and clearly. Doesn't seem to be as impacted by mains noise? Seems to give a cleaner signal than the breathing belt.
