Data and Matlab package for Using imaging photoplethysmography for heart rate estimation in non-human primates

Raw data for imaging photoplethysmogram extraction collected in 10 recording sessions from four rhesus monkeys and Matlab scripts for their processing.<br>For details of the study please refer to [1].<br><br>INSTRUCTIONS:<br>1. Please download the zip-archive and unpack its contents. <br>2. Please launch the script dataset_analysis.m in MATLAB to reproduce the results described in [1]. For a detailed description of the code please see [2].Matlab scripts require Matlab Wavelet Toolbox.<br><br>DATA DESCRIPTION:<br>Data of session N is placed in a folder SessionN. <br>Data for sessions 1-8 consist of four files:<br>SessionN.bin - raw color signal data in binary file, in format r1 g1 b1 r2 g2 ....;<br>SessionN_ROIdata.txt - metadata of ROI used for data color signal computing;<br>SessionN_interframeDif.txt
- interframe differences in the video, proxy for the amount of motion.
Format: stream of double values with a new line symbol as delimiter, use <br>a = load('SessionN_interframeDif.txt', '-ascii') to load in Matlab;SessionN_REF.csv - average reference pulse rate values for time intervals of length reported in file summary.txt.<br><br>Data for session 1 additionally contain the following files:<br>Session1RegionN.bin - raw color signal data in binary file for Section 1 with ROI different from region 3; <br>Session1RegionN_ROIdata.txt
- metadata of ROI used for data color signal computing for Section 1
with ROI different from region 3;<br><br>Data for sessions 2IR, 9IR and 10IR consist of three files:<br>SessionN.bin - raw "color" (effectively - monochrome) signal data in binary file, in format i1 i1 i1 i2 i2 i2 ...;<br>SessionN_ROIdata.txt - metadata of ROI used for signal computing;<br>SessionN_REF.csv - average reference pulse rate values for time intervals of length reported in file summary.txt.<br><br>REFERENCES:<br>[1] Unakafov AM, Möller S, Kagan I, Gail A, Treue S, Wolf F (2018) Using imaging photoplethysmography for heart rate estimation in non-human primates. bioRxiv. doi:10.1101/252403<br>[2] Matlab package "Imaging photoplethysmogram extraction and pulse rate estimation". https://de.mathworks.com/matlabcentral/fileexchange/67527-matlab-package--imaging-photoplethysmogram-extraction-and-pulse-rate-estimation-<br><br><br>
