%% EMG_OptitrackSync_Biopac_updated

%Updated by Ashley MontJohnson on 3/29/2022

%

% Updated by Erick Nunez on 8/26/2025

% – Updated library location

% – Updated library version

% – Updated mptype value to 104 for MP36A box

% – Updated channelpresent.xml file location

% – Tested with all 4 channels

% – Tested with Duo camera (Sync output: Recording Gate, Inverted)

%

%This code sets up the biopac connection & settings. Then it will ask for a

%time (in seconds) for how long you want the experiment to run. From there

%it will count down and instruct you to hit record in Motive. Once you hit

%record you will see the Figure 1 box pop up with the EMG recording in real

%time. The EMG recording will end and you will be given an elapsed time

%(should be very close to the time you entered). Then you will enter a

%trial name. Then you will be instructed to go to motive and stop da10ta

%collection. IT IS IMPORTANT TO NOTE THAT THE START TIME WILL BE THE SAME

%BUT THE MOTIVE DATA WILL RUN LONGER – YOU MUST CUT THIS OUT IN POST

%PROCESSING OF THE MOTIVE DATA. You know when data collection ended with

%EMG in matlab from your time vector. Don’t forget to export Motive data

%separately!

%(should be very close to the time you entered). Then you will enter a

%trial name. Then you will be instructed to go to motive and stop da10ta

%collection. IT IS IMPORTANT TO NOTE THAT THE START TIME WILL BE THE SAME

%BUT THE MOTIVE DATA WILL RUN LONGER – YOU MUST CUT THIS OUT IN POST

%PROCESSING OF THE MOTIVE DATA. You know when data collection ended with

%EMG in matlab from your time vector. Don’t forget to export Motive data

%separately!

Just do the 2 slides with Amanda next to them in the midterm outline doc you can just inform me on what to write no need to make new slides
