NDTS installations on the spectrometer workstation are comprised of the daemon which runs as a service and the NDTS graphical user interface (NDTS-GUI) which provides status information and allows users to make changes to harvesting status, NAN user, and metadata that will be associated with datasets. NDTS is designed to automatically harvest datasets as they complete when harvesting is set to "on", but datasets can also be manually harvested through the NDTS-GUI.
NDTS installations on the spectrometer workstation consist of the daemon, which runs as a service, and the NDTS graphical user interface (NDTS-GUI), which displays status information and allows users to adjust harvesting status, select the NAN user, and provide metadata to be associated with datasets. NDTS is designed to automatically harvest datasets upon completion when harvesting is enabled. Manual harvesting can also be performed via the NDTS-GUI.
 
'''Important Note: For TopSpin 4.x and VNMRj the daemon will automatically detect when experiments are complete, but for TopSpin < 4.x each user must enable Accounting from their TopSpin account for the daemon to recognize when experiments complete'''

Datasets harvested need to be associated with a NAN user to allow the datasets to be visible from the Dataset Browser. This is primarily done through the NDTS-GUI where the NAN user may be changed (if the facility manager settings permit the action). By default the NAN user mapped to the spectrometer workstation is selected. The mapping is controlled by the NMR facility manager through a user management page on the NAN portal facility dashboard.
Each harvested dataset must be associated with a NAN user to be visible in the Dataset Browser. This association is managed primarily through the NDTS-GUI, where the selected NAN user can be changed (if permitted by facility manager settings). By default, the NAN user mapped to the current spectrometer workstation user is selected. These mappings are managed by the NMR facility manager through the user management page on the NAN portal Facility Dashboard.

From the Facility Dashboard facility managers use the Manage Facility Users tool to add NAN users to their facility, map those users to spectrometer workstation accounts, set default harvesting settings, and decide how to handle cases where the spectrometer workstation user is not mapped to a NAN user.
Facility managers use the ''Manage Facility Users'' tool on the Facility Dashboard to:
* Add NAN users to the facility
* Map users to spectrometer workstation accounts
* Set default harvesting preferences
* Define fallback behavior for unmapped users


When the NDTS-GUI is launched, or when the NAN user selected within the NDTS-GUI is changed, the default settings defined in the Manage Facility Users tool on the NAN web portal are refreshed to the default settings.
When the NDTS-GUI is launched or when the selected NAN user is changed, the default harvesting settings are refreshed based on the configuration in the *Manage Facility Users* tool.


If the NDTS-GUI is not running, than NDTS harvesting falls back to the default settings defined in the Manage Facility Users tool
If the NDTS-GUI is not running, NDTS harvesting defaults to the fallback settings defined in the ''Manage Facility Users'' tool.


== Launching the NDTS-GUI ==
== Launching the NDTS-GUI ==
As the harvesting settings will default to the settings defined in the Manage Facility Users tool it is important that the NDTS-GUI is running at all times so that the harvesting status is visible, and users have the ability to make changes before data collection to ensure proper harvesting and metadata. For this reason, once started the NDTS-GUI has the close button disabled to avoid accidental closing of the application. Users should also setup the NDTS GUI to launch automatically when logging in graphically to the spectrometer workstation.  
It is essential that the NDTS-GUI remain running so that harvesting status is visible and users can ensure appropriate metadata and settings are applied before data collection. To prevent accidental closure, the close button in the GUI is disabled once launched. It is strongly recommended to configure the NDTS-GUI to start automatically upon login to the spectrometer workstation.

While it is better to automatically launch the NAN-GUI upon login, it may be launched manually with the command

Below are instructions for different desktop environments, but with so many different versions and different Linux distros it is impossible to cover all possibilities.

** This value is defined by the facility manager and can be changed in the daemon configuration file. This allows users to run calibration and other experiments that they do not want to be harvested in job numbers higher than the set value where they will not be harvested and avoids the need to toggle harvesting off for such datasets where it is easy to forget to turn it back on.

** Having the correct NAN user selected is important as only the NAN user, their PI, and the facility manager will have access to the datasets within the Dataset Browser. Data associated with the incorrect user can be rectified by the NAN User or PI as long as the true NAN user is within the same lab group or by the facility manager who has the ability to reassign the data to any NAN user.

Disallowing harvesting to be turned off can ensure that all data is collected while still allowing users to utilize high job numbers for cases where a calibration or test experiment to not be collected.

Overview

NDTS installations on the spectrometer workstation consist of the daemon, which runs as a service, and the NDTS graphical user interface (NDTS-GUI), which displays status information and allows users to adjust harvesting status, select the NAN user, and provide metadata to be associated with datasets. NDTS is designed to automatically harvest datasets upon completion when harvesting is enabled. Manual harvesting can also be performed via the NDTS-GUI.

Important Note: For TopSpin 4.x and VNMRj the daemon will automatically detect when experiments are complete, but for TopSpin < 4.x each user must enable Accounting from their TopSpin account for the daemon to recognize when experiments complete

Instructions for turning on Accounting for TopSpin < 4.0

Mapping NAN users to spectrometer workstation users

Each harvested dataset must be associated with a NAN user to be visible in the Dataset Browser. This association is managed primarily through the NDTS-GUI, where the selected NAN user can be changed (if permitted by facility manager settings). By default, the NAN user mapped to the current spectrometer workstation user is selected. These mappings are managed by the NMR facility manager through the user management page on the NAN portal Facility Dashboard.

NDTS harvesting defaults

Facility managers use the Manage Facility Users tool on the Facility Dashboard to:

  • Add NAN users to the facility
  • Map users to spectrometer workstation accounts
  • Set default harvesting preferences
  • Define fallback behavior for unmapped users

When the NDTS-GUI is launched or when the selected NAN user is changed, the default harvesting settings are refreshed based on the configuration in the *Manage Facility Users* tool.

If the NDTS-GUI is not running, NDTS harvesting defaults to the fallback settings defined in the Manage Facility Users tool.

Launching the NDTS-GUI

It is essential that the NDTS-GUI remain running so that harvesting status is visible and users can ensure appropriate metadata and settings are applied before data collection. To prevent accidental closure, the close button in the GUI is disabled once launched. It is strongly recommended to configure the NDTS-GUI to start automatically upon login to the spectrometer workstation.

Manually launching the NDTS-GUI

While automatic launching is preferred, the GUI can be started manually with:

/opt/nan-dtdaemon/nan_gui

Automatically launching the NDTS-GUI

The setup depends on the desktop environment and whether the configuration is per-user or system-wide. Below are instructions for different desktop environments, but with so many different versions and different Linux distros it is impossible to cover all possibilities. That said, launching an applications upon login is a common task as the correct answer can usually be found easily with a Google search or by asking one of the LLMs such as ChatGPT.

Step 1: Identifying the desktop environment

Use this command to determine your current desktop environment

echo $XDG_CURRENT_DESKTOP

if the above command does not work or show output try:

echo $DESKTOP_SESSION

Step 2: Creating the launcher script (if adding from the CLI)

If you are adding the launcher script through the command line interface you will need to create the text file below using your favorite editor and save it to the appropriate location (see the table below of the CLI-based path)
