In the MESA actigraphy dataset, the raw measurements of the accelerometer data are not available. Is it possible to get access to the raw files? This will help researchers build novel algorithms that can identify sleep stage using accelerometer data.

Thanks for the suggestion - I agree raw accelerometry data will be helpful to researchers. Unfortunately, the device used in MESA and HCHS - the Philips Actiwatch Spectrum - does not output raw accelerometry data. It only outputs activity/light data into binned epochs, e.g. 30 seconds. For future datasets with accelerometry data we plan to make those data available for download.
