Downloading the data in MATLAB format.

The dataset can be downloaded in MATLAB format from here.

Importing the data into MATLAB

If you want to reproduce the process used to obtain the data in MATLAB format from the original dataset, then follow these steps:

1. Download from here or here, and unzip.
2. Download the convert_subject_pickle_files_to_mat.py python script.
3. Copy the subject's .pkl file to the same folder as this python script.
4. Run the python script to convert the .pkl file into a MATLAB file. (I used Spyder - a Python program - through Anaconda-Navigator.)
5. Copy this MATLAB file back to the same folder as the .pkl file was obtained from.
6. Download collate_ppg_dalia_dataset.m MATLAB script.
7. Modify the MATLAB script by inserting the up.paths.root_folder and up.paths.save_folder into the setup_up function.
8. Run the MATLAB script to collate all the individual MATLAB files into a single MATLAB data file, ready for analysis.
