+# physionet_ECG_data
+This repository contains human electrocardiogram data (ECG) data used in MathWorks' Wavelet Toolbox machine and deep learning examples.
+This data is sourced from https://www.physionet.org/. In keeping with PhysioNet's copying policy, the ECGData.zip file contains a 
+.txt file, Modified_physionet_data.txt, which contains the specific attributions for the orignal PhysioNet source databases as well as
+a description of all data modifications.
+
+Important Note:
+Examples in some versions of MATLAB reference the downloaded .zip file in text and code as ending in ```-master.zip```. To avoid errors in 
+execution, replace instances of ```-master.zip``` in code with ```-main.zip```.
+
+For example:
+
+```>>unzip(fullfile(tempdir,'physionet_ECG_data-main.zip'),tempdir)```
+
+```>>unzip(fullfile(tempdir,'physionet_ECG_data-main','ECGData.zip'),...```
+
+```    fullfile(tempdir,'ECGData'))```
+
+If you use ```git clone https://github.com/mathworks/physionet_ECG_data``` to download the data, the .zip file is "ECGData.zip" in your
+physionet_ECG_data folder.
