The RPoint in csv file can't match the r point in edf from mesa database. For example, the first row of RPoint in mesa-sleep-0001-rpoint is 149, but the first r point in mesa-sleep-0001.edf is about 54. My object is to get hrv, brv, cpc features and the corresponding sleep stage label.
Thanks - if you have an algorithm to detect the EKG-related data yourself then I recommend using that. The information on the HRV page (https://sleepdata.org/datasets/mesa/pages/hrv-analysis.md) is all the information we have. I believe only the R-points in sleep were intended to be reviewed.
