Introduction

A DFX Point is a biosignal of interest that is assigned a unique name on the DeepAffex Cloud. (e.g. HR_BPM is the DFX Point for heart rate.)

A DFX Study is a collection of DFX Points that are computed in one measurement. A Study is based on a Study Template which determines which Points it contains. You can list the Studies available to you, retrieve a Study's details and select one for use in measurements.
