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.
