The following data are provided from the PPG Diary 1 Study. Definition: PPG - photoplethysmogram Versions: Preliminary Subsets v.0.1: Three subsets are provided: (i) a one-hour recording of simultaneous red and infrared PPG signals; (ii) a one-minute recording of infrared PPG signal; (iii) a recording of a single pulse wave, acquired using infrared PPG. Each recording was acquired from the same subject during sleep. The recordings are provided in Matlab ® format. v.1.1 - Complete Dataset: The complete dataset is provided in the Matlab ® file named ppg_diary_pilot_conv_data.mat. The contents of the file are described in the README file named ppg_diary_pilot_study_data_README.txt . In addition, the Matlab ® codes used to analyse the dataset are also provided: ppg_diary_pilot1_analysis.m (which is the main function), and PulseAnalyse (v.1.2beta, which is called by the main function). Instructions on how to use the codes to analyse the dataset are provided here. v.1.2 - including the Submitted Manuscript: The submitted manuscript is available here. Further Information Further information of the PPG Diary Project, and the data provided here, is available at: https://peterhcharlton.github.io/ppg-diary/
