empatica_zip

This data stream handles Empatica sensor data downloaded as zip files using the E4 Connect.

Container

You need to create a subfolder for every participant named after their device id inside the folder specified by [EMPATICA_DATA_STREAMS][empatica_zipfiles][FOLDER]. You can add one or more Empatica zip files to any subfolder.

The script to connect and download data from this container is at:

src/data/streams/empatica_zip/container.R

Format

The format.yaml maps and transforms columns in your raw data stream to the mandatory columns RAPIDS needs for Empatica sensors. This file is at:

src/data/streams/empatica_zip/format.yaml

All columns are mutated from the raw data in the zip files so you don't need to modify any column mappings.
