NMRanalyst automates the analysis of multidimensional NMR spectra. The NMRplot application provides the link between the visual and NMRanalyst's automated analysis. The quality of NMRanalyst results can be visualized using experimental, simulated, and residual 1D through 3D spectra. Derived information such as phase functions, correlation locations, NOE build-up curves, and detailed area plots can also be visualized. This chapter describes the NMRplot application with its interactive features.
NMRplot can be started by the Graphic workwindow. If the specified plot file is in NMRanalyst spectral file format, the spectrum is phase corrected by the phase functions specified in the
F1 Phase =,
F2 Phase =, and
F3 Phase = input fields in the Graphic workwindow before plotting. See CHAPTER 16: "Report Workwindow" and SECTION 18.3: "Multidimensional Spectrum Specific Settings" for details.
The NMRplot application supports the following mouse interactions:
Left mouse button
Middle mouse button
Right mouse button
[Ctrl] left button
On a two-button mouse, the missing middle mouse button is emulated by holding the
[Shift] keyboard key and pressing the left mouse button. Two-dimensional contour, 2D location plots of correlation signals, precision distribution, integral values, phase function, 1D parameter, 1D spectrum, and build-up curve plots support zooming and moving, but not rotating or spinning. For these 2D plots, pressing and dragging the left mouse button draws a rectangular box (rubber-band) over the displayed spectrum; upon release of the left mouse button, the spectral area inside the rubber-band is enlarged. To abort a rubber-band zooming, type the
[Esc] keyboard key before releasing the left mouse button. The display of these 2D plots can be shifted to a different area. Press the middle mouse button over the displayed area and drag the mouse in the desired direction. The edge of the acquired spectrum is indicated by a red dashed line. Upon the completion of a rubber-band zoom or shift, the axis labels update.
Pull-down menus are located at the top of the NMRplot window. Besides mouse interactions, the menus and menu items can be activated by typing the
F10 keyboard key and navigated through the left, right, up, and down arrow keys. Not all menus and menu items apply to each plot type. So only applicable menus and menu items are shown for a displayed plot. Details of each menu and menu item are discussed below:
[Save PostScript...]saves the displayed plot as a color PostScript file. It starts a Filebox popup for specifying the file name. The
Ctrl+Sdisplayed at the right hand side is the keyboard short-cut for this menu item.
[Print]sends the color PostScript file of the displayed plot to the printer specified in the NMRanalyst Print Settings popup.
[Exit]exits the displayed NMRplot application.
[Reset]returns to the display with which NMRplot started.
[Previous Zoom]restores the previous rubber-band zooming level.
[White Background]switch the background color for displayed and saved plots.
[Perspective Projection]switch perspective for the plot off and on, respectively.
[Surface]renders the displayed surface or iso-surface plot as filled surfaces.
[Wireframe]shows such plot in wireframe representation. For 2D contour plots,
[Horizontal F2]display F1 and F2 respectively along the horizontal (i.e., X) axis. For 2D surface plots,
[F2 Side]reorient the spectrum to show the corresponding side of the spectrum. For 3D spectral displays,
[F3-F1 Side], and
[F2-F1 Side]show the corresponding spectrum surface.
[Overlay]menu applies to 2D contour, 3D isosurface, 1D spectrum, and phase function plots. The items in this menu selectively switch the visibility of displayed components on and off. For 2D contour and 3D isosurface plots,
[nD Positive Signals],
[nD Negative Signals], and
[nD Correlation Locations](if specified) display/hide the positive signals, negative signals, and correlation locations respectively.
For 1D spectrum plots,
[1D Experimental Spectrum],
[1D Simulated Spectrum] and
[1D Residual Spectrum] plot the selected spectra. The residual spectrum is the difference between experimental and simulated spectra.
[1D Component Resonances] plots the individual overlapping signals of which the sum is equal to the simulated spectrum.
If a 1D spectrum is added to the F1 or F2 dimension of a 2D contour plot,
[1D Experimental Spectrum],
[1D Simulated Spectrum] and
[1D Residual Spectrum] menu items are shown for displaying/hiding the selected 1D spectra.
For phase function plots, F1, F2, and F3 (for 3D spectra only) phase components can be displayed or hidden by toggling
[F2 Phases], and
[F3 Phases] respectively.
[Component]menu applies to 1D spectrum plots, 2D contour plots, 2D surface plots, surface plots of 2D fitting areas, and isosurface plots of 3D fitting volumes. For the 1D plots, the selected item determines whether the absorption or the dispersion mode of a 1D spectrum is displayed. For the 2D and 3D plots, the selected item determines the displayed phase component. A phase component is specified in the order F1 F2 F3, and R stands for real and I for imaginary. After phase correction, R contains the absorption mode and I the dispersion mode resonances. For 2D F1 phase-insensitive spectra, the
[II]items in this menu are deactivated.
[Unit]menu applies to 2D contour, 2D surface, 3D isosurface, 2D and 3D correlation location, 1D spectrum, and 1D parameter plots. The selected item determines the unit displayed along the spectral axes.
[Build-up Curves]menu is only shown for plots of build-up curves.
[Next Plot]menu items can be selected to scroll through all build-up curves.
[Nmrplot...]displays the current manual chapter.
[Tutorial...]shows Tutorial II with application examples. The NMRplot application is started by the Graphic workwindow. Files displayed by NMRplot can be created by the 1D Analysis, nD Analysis, and Report workwindows. The menu items
[1D Analysis Workwindow...],
[nD Analysis Workwindow...],
[Report Workwindow...], and
[Graphic Workwindow...]display the manual chapters on the 1D Analysis, nD Analysis, Report, and Graphic workwindows, respectively.
[About NMRplot...]shows program version information.
