• Downloading NMR data to a computer in your lab involves connecting to one of the NMR data stations using the Secure File Transfer Protocol (sftp). There are graphical clients available for MacOS and Windows.

• If you are downloading to a Macintosh, the applications Fetch, Macfusion and Cyberduck are available.

• If you are downloading to a PC running Windows, the available software includes Filezilla and WinSCP.

• If the necessary applications are not available on your computer, ask the RSC Computer Unit to install it for you.

• If you are downloading NMR data from outside the RSC, you will need to run GlobalProtect to access your data.

Procedure

1. Whatever application you are using, make sure the connection method is set to sftp not ftp since the NMR data stations will refuse connections which use ftp because it is less secure.
   They will also refuse connections from computers outside the RSC.

2. Start the application. Connect to a computer from the table below...

   NMR was run on...	connect to hostname	Username	Directory
   Top floor Avance 400	ernst	av400bb +	data/your group name
   Middle floor Avance 400	abragam
   Avance 400 in NMR Suite	gutowsky	your group name	/opt/data/your group name/nmr #
   Avance 600	ramsey
   Avance 700	rabi
   Avance 800	bax
   MR400 *	rabi		/opt/mr400/your group name %
   Mercury *	rabi		/opt/old_vnmr_data/mercury/fids/your group name %
   	ernst	av400bb	/home/av400bb/mercury%

    

   ⁺   The av400bb password is in part 2 of the Retrieving your spectrum section in the Av400 Guide folders in rooms 2.66 and 3.66.
   ernst and abragam are the data stations that share NMR data with the spectrometer computers.

   ^#   Data from the 600, 700 and new 800 can also be retrieved from the computer "waver" in the directories "Av600", "Av700" and "Av800" respectively. Log in as user "mercury".
   Topspin 3 is not picky about where you store your data, so if you elected to save it somewhere other than the directory given in the table above when you ran it, you will need to remember its location.
   

   ^%   If you still don't see your data, look inside the 00-OldFIDs subdirectory.

   *   Old Varian spectrometer no longer used in the RSC.

    

    
   The graphic on the left below shows the connection screen for Fetch (with the wrong hostname for mercury and MR400 data). The user has entered the name "fids_mr400" as the initial folder, but it is possible to leave this blank, and navigate to the folder of interest by double-clicking on displayed folders.

3. Navigate to the directory (a.k.a folder) where your FIDs are stored. The navigation method will vary depending on the application you are using. In Fetch simply double-click on a directory in the list to enter it. In the graphic on the right above, a user has connected to bloch as user banwell, and entered the fids subdirectory (a.k..a. "banfids").

4. In Fetch, click on the data set of interest, and click on Get to copy it to your computer. The method of retrieving data sets will differ for other applications, some of which use a drag and drop interface.

5. Repeat the previous procedure for all data sets of interest, then exit from your application.
