 GenECG is divided into the following subsets:
 
--Dataset A: ECGs without imperfections (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 A: ECGs without imperfections (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 (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.
+-Dataset B: ECGs with 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 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.
