Connects to the Data Manager to display and control patient and measurement meta-data

Data Browser

Overview

This operator allows to browse and search patient and measurement data in the Data Manager.

Patient records ("Patient Record") and measurement sessions ("Measurement Session Record") can be stepped through, and using intelligent queries, specific patient data can be obtained.
