how have you appended the two channel data in this example?

Hello,

I have a query regarding the two channels for each of the 105 patients. You said each channel of 105 two-channel ECG was labelled, for a total of 210 ECG signals stored together with 210 MAT-files.

Have you merged the two-channels like 1, 2, 3, 4 .. 210 with alternate channels of each patient? Or have you taken all 1stchannels from all patients, and then appended all 2nd channels from all patients?

Please advise, thank you.

Regards,

Vaibhav

As per my understanding after seeing the example Waveform Segmentation Using Deep Learning and cheking the modified dataset and actual dataset, the file ecg209.mat corresponds to channel 1 of the patient & ecg210.mat corresponds to channel 2 of the same patient.

To summarize, for a patient x (1 <= x <= 105) the ecg2*x - 1.mat file corresponds to channel 1 & ecg2*x.mat corresponds to channel 2. (Note that * refers to multiplication)

Many thanks Srivardhan.
