Code related to the evaluation of Sleep Period Time window detection algorithm in the Newcastle PSG study

preprocess_acc_data.R

Use R package GGIR to pre-process the accelerometer binary files, e.g. feature extraction and autocalibration.

transferdatatocsvfiles.R

Script to load the output from GGIR and store relevant data in separate csv files.

newcastlepsg-acc-spt-detection-eval.R

Script to match PSG and accelerometer files and perform the comparison between PSG sleep scores and accelerometer derived sleep classifications. Function calculate_hdcza.R is used to detect the SPT-window with algorithm HDCZA.
