NMR Service - Frequently Asked Questions
Every ten minutes NMR data are automatically transferred from the spectrometers to a data server. Users access their data from this server using GetFile running on Windows PC. This system allows us to improve the security of the spectrometer workstations.
Data of the different spectrometers can be found in the following directories:
In order to facilitate the search of recently acquired data, a copy of all data is stored during a couple of weeks in a user directory. Its name corresponds to the first two letters of the experiment name, which should be the user's initials.
In these directories, the experiment name has a prefix made of two letters followed by an underscore ("_").
The first letter corresponds to the first letter of the group ("g" for "guest", "l" for lacour, etc.).
The second letter indicates the Larmor frequency of the spectrometer ("5" for the 500 MHz, etc.)
For example "g4_djpcf27" corresponds to the dataset "djpcf27" stored as "guest" on the 400 MHz spectrometer.
