%% 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

Review all of the documents except your Team’s document. Something I haven’t mentioned yet: Record the time you spent reviewing each of the documents.

Remember to provide two (soft preferred) copies of your comments for each of the 2 documents to the class (you don’t have to write comments on your own team’s document) and me. The comments are written on the document either in hand or via the TRACK CHANGES feature of WORD. Make sure you include the time you spend on reviewing each of the documents.

Attached are the documents.

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

I have entered the data and sample labs from other people you can reword them just make sure u imput mu data in the code

Make me a short research slides presentation on any research papers just follow the rules and show me the different ways to show the data and make short speaker notes. Do not over complicate it do not worry give the simple graphs and follow the rules.i only need to speak for 3 mins.

Read these articles .

2. Choose one figure from each paper and prepare one observation about the

presented data (so two answers total).

3. Describe the experimental groups and why they were chosen.

4. Describe how the data was used to differentiate between experimental groups.

5. Describe how statistics was used in the interpretation of the experimental

question.

6. Be prepared to present their arguments during class.

I thought of this research topic on new ways to restore cardiac function in rat models.

I plan to focus on two studies: one about inhibiting DPP3 to improve heart function in sepsis, and another about using VCAM1-expressing cardiac fibroblasts to improve heart function after a heart attack. I will compare their methods, results, and possible future applications.
