The NDTS GUI displays the currently selected NAN user. However, it is the NDTS daemon that tracks the local workstation username and the selected NAN username. If the NDTS GUI loses communication with the NDTS daemon for an extended period (50 seconds), the daemon will revert to an unspecified user. In this case, the NDTS GUI may become out of sync with the daemon. This safeguard prevents data from being mistakenly harvested under the wrong user if the GUI loses connection to the daemon.

How do I know if this occurred?

You can identify this condition in several ways:

  • The NDTS daemon log file will report that contact with the GUI was lost for 50 seconds and that it is defaulting to the unspecified user's NDTS harvesting settings.
  • In the NDTS GUI, select Enter Experiment Details. This probes the daemon and shows the actual currently selected user. From there, you can re-select your NAN username, and the GUI will update accordingly.
  • The NDTS audit file will log the experiment endings, whether they were harvested (based on the unspecified user defaults), and that the NAN user was "unspecified".

How to correct the situation?

In the NDTS GUI, click on Enter Experiment Details and re-select your correct NAN username. All subsequent datasets will then be harvested under the proper username.

How to get the missing datasets into my data browser?

Datasets collected while the user was unspecified may or may not have been harvested, depending on the default settings for the unspecified user set by your NMR facility manager.

  • If the datasets were harvested — ask your facility manager to reassign them to your NAN user.
  • If the datasets were not harvested — log in to the NMR spectrometer workstation and use the Manual Harvest option in the NDTS GUI to select and harvest the missing datasets.

Important: If a dataset was already harvested under the unspecified username, the Manual Harvest window will issue a warning. In this case, it is strongly recommended that you contact your facility manager to reassign the dataset, rather than forcing a manual transfer, to avoid creating duplicate entries in the system.
