Downloading NMR data to a computer in your lab
- 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.
- These instructions are not meant to imply that it is necessary to
transfer your NMR data to a computer in your lab. NMR data on the
spectrometers, and also on the data station bloch is backed
up regularly to another computer in the School, so there is no possibility
of your data being lost. However some users may wish to transfer data to a
computer in their lab because they have their own processing software installed.
- 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.
- 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||av400bb +||data/your group name|
|Avance 600||ramsey||your group name||/opt/data/your group name/nmr #|
|MR400||waver||mercury||fids_mr400/your group name %|
|Mercury||bloch||mercury||fids/your group name %|
+ 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.
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
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.

* This assumes you used the xfer command to
transfer your data to bloch after saving it.
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.
- 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").
- 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.
- Repeat the previous procedure for all data sets of interest, then exit from
