NAN Data Transport System

NDTS Facility Manager Guide

The Network for Advanced NMR Data Transport System (NDTS) enables automated harvesting of NMR acquisition data directly from spectrometer workstations and delivers it securely to the NAN Repository. Facility Managers are responsible for installing and managing the NDTS components, ensuring connectivity, and supporting data access for users.

NDTS Architecture Overview

NDTS consists of two core components:

• NDTS Daemon – Runs on each spectrometer workstation. Detects completed acquisitions, manages user and experiment metadata, and transfers data to the gateway.
• NDTS Gateway – Runs on a central server at the facility. Receives data from all workstations and forwards it to the NDTS Receiver at UCHC.

Data Flow Summary

1. An experiment ends on the spectrometer workstation.
2. The NDTS Daemon detects it, packages the data, and attempts to send it to the Gateway.
3. The Gateway relays the data to the Receiver.
4. Once received, the data becomes available in the NAN Repository within seconds.

If a connection fails at any stage, data is spooled and retried until successful.

NDTS Responsibilities for Facility Managers

Facility Managers are expected to:

• Install and configure NDTS Gateway and Daemon software
• Monitor daemon heartbeat and transmission status
• Support users in selecting the correct metadata (e.g., NMRhub usernames)
• Reassign “unselected” or misattributed data
• Use the Facility Dashboard to review transmission health and harvested data
