How could I transfer my data from the spectrometer to my workstation?

The best way is probably to use GFTP, a graphical user interface to FTP (file transfer protocol).

Suppose you want to send the NMR dataset
/opt/topspinr/data/tali/nmr/myfile
from the spectrometer (where it was acquired) to a Linux PC named HELIX.

  • From a Unix shell on the spectrometer evoke the program gftp.
  • On the left side of the appeared window, the details of the local station (the spectrometer) appear.
  • Choose the directory (Dir) where your dataset resides (e.g. /opt/topspin/data/tali/nmr), and
  • Mark your dataset name (e.g. myfile).
  • Fill in the name of your workstation (Host , e.g. HELIX),
  • Your userid there (User, e.g. tali ), and
  • Enter your password (Pass).
  • On the left side of the gftp window, choose the directory into which you want your data to be transferred to, and
  • Transfer the selected items by clicking on one of the two arrows
  • Be sure first to set the correct file transfer mode (ASCII / BINARY): choose ASCII for transferring your NMR dataset.
  • When the transfer was completed, quit the program ( file -> quit).
Another way to transfer data, if GFTP is not installed

In case you are willing to transfer the NMR data use the tar command. The tar command saves and restores multiple files on a single file. For transferring dataset
/opt/topspin/data/tali/nmr/myfile
 

cd /opt/topspin/data/tali/nmr
tar cvf myfile.tar myfile

Next transfer the file myfile.tar to your workstation

How can I extract my files once transferred?

In order to extract your data (e.g. to copy it to the directory /opt/topspin/data/tali/nmr) on your workstation, follow the instructions:

  1. cd /opt/topspin/data/tali/nmr
  2. tar xvf myfile.tar

This will extract the dataset myfile and copy it back to its original location on the disk.

How could I send a data set to Bruker?

Suppose you want to send the NMR dataset
/opt/topspin/data/tali/nmr/myfile
Perform the following steps:

  1. cd /opt/topspin/data/tali/nmr
  2. tar cvf myfile.tar myfile
  3. gzip myfile.tar (creates myfile.tar.gz)
  4. ftp ftp.bruker.de (acces the ftp server)
  5. login as anonymous
  6. cd /incoming
  7. put myfile.tar.gz
