I would like to acquire EMG, torque/angle (from isokinetic dynamometer), and stimulation data via Matlab. I have a chassis system that is connected to my computer with Matlab. When the stimulation is given, I would like it to trigger the system such that Matlab records and shows me the next 0.3s of data (i.e., to visualize M-wave).
Does anyone have a Matlab script they could share with me?
Para adquirir ondas M en Matlab, es necesario utilizar algún tipo de hardware que pueda capturar las señales de microondas y convertir los datos digitales que Matlab pueda procesar. Por ejemplo, se podría utilizar un receptor de microondas conectado a un hardware de adquisición de datos (como una tarjeta de adquisición de datos) y luego leer los datos en Matlab.
A continuación, se presenta un esquema general para la adquisición de ondas M en Matlab:
El código varía dependiendo del hardware específico que esté utilizando y los detalles de la adquisición de datos que se necesiten.
Matlab script to acquire EMG, torque/angle data from an isokinetic dynamometer, and stimulation data, and visualize the next 0.3s of data after a stimulation event:
```
%% Set up data acquisition
s = daq.createSession('ni');
s.Rate = 1000; % Sampling rate in Hz
% Add analog input channels (EMG and torque/angle)
addAnalogInputChannel(s, 'dev1', 0:1, 'Voltage');
% Add digital input channel (stimulation trigger)
addDigitalChannel(s, 'dev1', 'Port0/Line0', 'InputOnly');
%% Start data acquisition
s.DurationInSeconds = 10; % Acquisition duration in seconds
[data, timestamps] = s.startForeground();
%% Process data
emg_data = data(:, 1);
torque_data = data(:, 2);
stim_trigger = data(:, 3);
% Find stimulation events
stim_events = find(diff(stim_trigger) > 0.5);
% Visualize next 0.3s of data after each stimulation event
for i = 1:length(stim_events)
event_time = timestamps(stim_events(i));
event_index = find(timestamps > event_time & timestamps
