Convert ecg file into .mat file for ECG classification

I am working on analysis of ECG signals for detection of heart abnormalities using pretrained CNN using the dataset from iRHYHTM. The dataset comes along with single ECG file and 7 json files for every recording. I want to convert them into .mat files to extract the features and label them.
The link to the dataset is here:

The .ecg files are in a binary format. I didn't see anything on the File Exchange about reading files that have an .ecg file extension. Do you have any information about the file format? What program creates these files?

Hi Rizwan,
As per my understanding, you would like to read “.ecg” files and store the values in .mat files.
You can achieve this using “fopen” and “fread” functions. Here is an example showing how you can do it:
fid1 = fopen('1.ecg','rt'); %Opening .ecg file for binary read access
A = fread(fid1,'*float32'); % Reading the data from an open binary file
save('output.mat','A') % Saving the data in .mat format
Please refer to the following MathWorks documentation for more information on –
I hope this resolves the issue you were facing.
