Accessing data from the spectrometers under Windows
spectrometers run the network service "samba" to export network shared
drives in a Windows-compatible format.
use it as a network drive under Windows, go to My Computer -> Tools
(or My Network
Places -> Tools in Windows 2000) and choose Map Network Drive.
Choose an unused drive letter. In the Folder box, put
the name of the spectrometer you wish to connect with, or the server:
(400 in Malott)
(400 in SBC)
(500 in Malott)
(400 in LSRL)
(800 in SBC)
and then click Connect using a different
user name. Enter the user name nobody and the password (ask the
NMR lab staff if you do not know)
and click OK. Click Finish in the Map Network Drive box; in a few
seconds, you should get a new directory view window of the topspin
usual, go down the tree data -> your username -> nmr to get to
the data folders. If you had samples run on the 800, the data is
probably in the nmrsu/nmr folder.
To do the same operation on a Mac, choose Go ->
Connect to server. In the box that appears, type
smb:// followed by a machine name as shown above. Note the
forward slashes here, back slashes for Windows. At the next step,
you will be
prompted for the name and password (same as above).
Everyone has read permission
to the data in all the trees (this is exactly the same as on the
spectrometer). Read permission also gives you permission to copy
to anyplace you have write permission (such as the desktop of your own
computer or Novell network drives you may have). The nobody
account does not have any write access. (Write
access in Linux also grants permission to delete files.)
The server has all of the archived data
available (currently about 290,000 Bruker spectra), stretching back in
some cases to 1997. The data1
folder contains a folder for each instrument which mirrors the layout
of its data, and you proceed down the directory tree to get it.
Non-data files (for instance, contents of your home directory with the
exception of directories ending in .fid on the Inova 600) are not
backed up. The server is updated each night from the spectrometers,
which means that the current day's data will not be visible on the
server. However, old data that has been removed from the
spectrometers should still be available there. There
are permanent network drives on the Linux workstations in 3002 Malott
and 104 SBC. The path is /opt/server and subdirectories take you
to archived copies of data from each of the spectrometers.
From off campus, you can access
the network drives, and get a license to run the ACD software, if
you set up and run the "KU Anywhere" VPN software on your
computer. It is accessed through the Kyou portal. Log in to Kyou
and you will see the link KU Anywhere in the upper right side of the
page next to Welcome, (your name).
If you click on this link, your computer will go through a security
check, download and start a Java applet, and you will have a secure
tunnel to the KU network and a KU network address. This allows
you to do most of the things you do on the KU network. Note that
this is a KU-wide network service and the NMR lab does not make or
troubleshoot these connections.
Accessing data from the spectrometers
We have three Linux workstations, two in 3002 Malott and one in 104
SBC, that have the spectrometer data directories, /opt/topspin/data,
mounted as network drives. These workstations also run
TopSpin. Log in to the workstation, double click on the TopSpin
icon or open a shell and type topspin. After TopSpin starts, the
left panel in the display will say Browser by default (if it doesn't,
click the Browser tab). Initially, the only directory tree in the
browser will be /opt/topspin. To view data from a spectrometer,
right click in the browser window and choose Add New Data Dir ... In
the window, type /opt/florence (=Malott 400), /opt/siena (=Malott 500),
/opt/yosemite (=SBC 400), /opt/bigsur (=LSRL 400), /opt/grandteton
(=800). Then you can expand the new data directory and navigate
down to your own data.
