E4tools

Tested with TravisCI: E4tools is an early-release set of tools that you can use to automate your workflow for analyzing EDA data that comes from the Empatica E4. You can run these functions consecutively.

What can you do now with E4tools?

There are currently four tools, all of which are part of the EDA workflow (acc. workflow coming soon):

The processing pipeline

E4_EDA_Process.part1.ExtractRawEDA, which allows you extract and filter EDA data. It will output raw data, filtered data (using user-specified high and low pass filters + a butterworth filter), and filtered + feature-scaled ([0,1]) data. It will also provide summary data at the participant and session level.

E4_EDA_Process.part2.ExtractButtonPresses, which allows you extract button pressess and remove pressess that are within a certain number of minutes before the end of a session or that are too close to another button press.

E4_EDA_Process.part3.MatchPressesToEDA, which allows you to extract the data that are within X minutes before and/or after a button press.

E4_EDA_Process.part4.BinMatchedEDA, which allows you to bin the data that has been matched to the button pressess (from step 3).

How do I structure my data for E4 tools?

Your files should be structured such that ZIP files should be grouped by participant – that is, each ZIP file (i.e., what you downloaded from Empatica Connect) is in a folder whose name is the participant ID.
