Read CSV file

[nikitako...@gmail.com]

Hi!

I would like to make QRS detection for ECG signal, which is written in CSV-file.

But this format is not readable for ECG-kit. How can I transform this file to readable format?

Hi Nikita and thanks for your interest, you can easily read the CSV format with Matlab, and then format as described in 

http://ecg-kit.readthedocs.org/en/master/Matlab_format.html

the ECG header variable should be created according to

http://ecg-kit.readthedocs.org/en/master/ECGwrapper.html#ecg-header-description

Keep me updated if you have more troubles with that. Good luck !

Best,

M.

Thank you!

So, I created such header file and tried to do:

ECGt_QRSd = ECGtask_QRS_detection();

ECGt_QRSd.detectors = {'wavedet'};

sig = csvread('C:\ecg_kit\RealHolterSample_48min.csv'); %read csv with 3 channels

sig = reshape(sig,[size(sig, 1)/3, 3]);  

save('C:\ecg_kit\RealHolterSample_48min.dat','sig'); %save to dat-file

ECG_w = ECGwrapper('recording_name', 'C:\ecg_kit\RealHolterSample_48min.dat')

ECG = ECG_w.read_signal;

So ECG != sig. I think that I make uncorrect saving. How can I save data in correct format?

Hi Nikita, you can check the file included in ecgkit_root/recordings/example_recording.mat to check the correct fields you must include in a .mat file.

Best !

Mariano.
