 GenECG is an image-based ECG dataset which has been created from the PTB-XL dataset (https://physionet.org/content/ptb-xl/1.0.3/).
 The PTB-XL dataset is a signal-based ECG dataset comprising 21799 unique ECGs.
 
-GenECG is divided into subsets:

+GenECG is divided into the following subsets:
 -Dataset A: ECGs without imperfections
 This subset includes 21799 ECG images that have been generated directly from the original PTB-XL recordings, free from any visual imperfections.
 
 -Dataset B: ECGs with imperfections
 This subset contains the same 21799 ECG images as Dataset A, but with added visual imperfections that simulate common issues found in photographed ECGs.
 
-The original PTB-XL metadata can be found in the CSV file: https://physionet.org/content/ptb-xl/1.0.3/ptbxl_database.csv
+The original PTB-XL metadata can be found in the following CSV file: https://physionet.org/content/ptb-xl/1.0.3/ptbxl_database.csv
 Images in the GenECG dataset have the same ecg_id as the PTB-XL dataset with the addition of _hr_1R to the ECG ID.
 For example, ECG 02000_hr_1R.png from GenECG corresponds to 02000_hr.dat in PTB-XL.
