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

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
