Copying NMR data to a USB memory stick
- The computers used for acquiring and storing data in the NMR Centre use the
Linux operating system. There are several styles of desktop available for Linux,
the most widely used being KDE and Gnome. The menu systems for these desktop
environments are different. The instructions below refer to the Gnome desktop
which is the one used on all the computers in room 238. This desktop has three
pull-down menus at the top left of the screen:
Applications Places System
- For ease of use, these notes decribe a "click and drag" method of copying files.
Another method, not described here, is to use the command line interface.
- Our systems are set up with four virtual desktops. Since the VnmrJ application
is usually occupying most of desktop number 1, it can be a good idea to go to
a different desktop to avoid clutter. To do this, click on one of the Desktops in
the tool on the right hand side of the bottom menu bar.
Remember to click on desktop 1 (which has the VnmrJ icon in the picture above)
when you're finished.
- Insert your USB memory stick into a USB slot on the computer. In room 238,
the data station nearest the door is the easiest one to get at. After a few
seconds a window will appear with icons representing the contents of the USB
The name of the USB stick will be in the title bar of this window.
- Click anywhere on the desktop background. You need to do this to make sure
the "focus" is not in the VnmrJ application. Then press Ctrl-L (hold down the
control and L keys, then release). A pop-up "Open Location" window will appear.
Enter "/home/mercury/fids/your-group_name" in the text entry area. (Replace
"fids" with "fids_mr400" if copying data from the MR400. If copying
data from one of the Inova or Avance spectrometers on a data station in room
G53, enter "/home/your-group_name/fids" instead).
- Click on "Open" in the above pop-up.
A second window will appear. This will
contain an icon for each of your datasets. If you can't find the data you are
looking for, double-click on the 00-OldFIDs icon, and look in the
sub-directories contained there.
- Drag or resize windows if necessary, so that both the USB stick window, and
the window containing your data are visible. Then drag the data of interest to
the USB stick window.
- When finished, you need to unmount the USB stick. In the USB stick window
select File then Unmount volume from the menu. (Some versions of
Linux may have an eject menu item instead). It is then safe
to remove the USB stick.
- Finally, close the windows that you opened in this procedure by clicking
in the "X" icon at the top-right of each window, and return to the virtual
desktop where VnmrJ is running.
