Windows and Axes

Each window within Analysis has a defined dimensionality (i.e. it is either 2D, 3D, 4D etc.) and the isotopes for each axis are fixed. So you might have windows with (x,y,z)=(1H,15N) or (1H, 15N, 13C) or (1H, 13C, 15N) or (1H, 1H, 15N) etc. When you open your first spectrum, Analysis will create a window for it to be shown in. However, in some cases the window may not be the one you want: for instance an HNCO is usually opened in a (1H,15N,13C) window, but personally I prefer to look at it in a (1H,13C,15N) type of window. If you open further spectra and windows already exist with the correct number and types of axes, then no new window will be created – instead the spectrum is shown in those windows which are already present. When no window is present in which the spectrum will fit, a new one is created.

You can create your own windows by going to the Windows pull-down menu and selecting New Window. Simply select what axes you would like and what isotopes they should be associated with. In the lower panel Analysis will show you if there are spectra which will fit into this window. If this is the case you have the option of selecting which (if any) spectra should be shown in this window (this is particularly useful when you have lots of spectra, as the program can get very slow if it tries to draw 20 spectra on top of one another in the new window).

If you want to duplicate a window, simply go to the Edit Windows option in the Windows pull-down menu. Select the window you want to duplicate and click Clone.

The Edit Windows pop-up has a number of useful features:
Aspect Ratio: this will change the relative scaling of the x and y axes – change this to make your peaks look more round or elongated.
If you have spectra with two axes belonging to the same isotope (e.g. (1H,1H)), then by default these have different Panel Types (e.g. H1 and H2). If you set them both to be H1, then your mouse will become symmetric across the diagonal and show two crossing-points rather than just one. This can be very useful for spectra such as 2D H-H NOESYs or solid-state carbon-carbon correlation spectra.
You can also select to see a 1D trace of the spectrum as you move across it with the mouse – displayed either on the mouse (X/Y cross-hair trace) or along the side of the spectrum (Side Trace). You can switch these settings on and off in the Edit Windows pop-up, but in practice it is easier to do this via the mouse under the Right Click / Window option. To change the scale of the 1D traces use the Home and End keys.
