Hello,

I am one of the authors of this database and I am glad you chose the BUT PPG database for your research. May I ask you what is your research dealing with?

More information about the database is included in this brand new article: https://www.hindawi.com/journals/bmri/2021/3453007/ .

The data are in standard WFDB format (very common on Physionet). This format (including .dat and .hea) can be read using WFDB toolbox https://archive.physionet.org/physiotools/matlab/wfdb-app-matlab/ .

I hope this helps. If you have any further question, feel free to ask.

Best regards,

Andrea Nemcova

To import dat files I use the mdfimport tool found on the Matab File Exchange
