1. Install WFDB Toolbox for MATLAB from https://physionet.org/physiotools/matlab/wfdb-app-matlab/
2. Run download_MITBIHDB.m to download the MIT-BIH database
  -- In the code, you need to determine the local path to save the database and the path for the installed WFDB Toolbox
For example:
  -- path_to_exes = 'path_to_WFDB_Toolbox\mcode\nativelibs\windows\bin';
  -- path_to_save_records = 'path_to_save_database';

3. Run seq2seq_mitbih_AAMI.m to prepare data for the intra-patient paradigm
 -- Modify the below line of the code based on your local address to the mitbih database
   --addr = '.\mitbihdb';
4. Run seq2seq_mitbih_AAMI_DS1DS2.m to prepare data for the inter-patient paradigm
 -- Modify the below line of the code based on your local address to the mitbih database
   -- addr = '.\mitbihdb';
