Display pull-down menu

This section describes the function of the most important buttons in the button panel (Fig. 4.2). Some of the additional options available within the Display pull-down menu in the main menu bar of 1D WIN-NMR and the function of scroll bars and function keys will be discussed in sections 4.5.2 and 4.5.3 respectively. All affect the display of a spectrum or FID in the ID WIN-NMR [Spectrum] window. The display buttons (Fig. 4.7) are available, whenever the ID WIN-NMR program has been started. 

When activating the Display pull-down menu (Fig. 4.7) the following functions are available ... 

Load the reference spectrum D NI /IRDATA GLUCOSE 1D H GHNO 1D 008999.IR from the NOE data for glucose. From the Display pull-down menu choose the Dual Display option and select the NOE-difference spectrum 007999.1 R in the same directory. 

Using the last data set inspect the Display Options menu available via the Display pull-down menu tor the normal, the dual and the multiple display modes. Try out the various effects of the various options. 

Load the H spectrum of glucose D NMRDATA GLUCOSE 1D H GH 002999.1 R. Use the Peak Picking button in the button panel for peak picking. From the Display pull-down menu choose the Display Colors menu. In the dialog box that appears on the screen select different colors for the spectrum, the frame, the numbers and the peak labels. Peak picking will be explained in more detail in section 4.6.2. 

In the Display pull-down menu select the inspect the corresponding dialog box.

From the series of selectively decoupled spectra of glucose load the reference spectrum D NMRDATA GLUCOSE 1D H GHHD 001999.1R. From the Display pull-down menu choose the Multiple Display option. In the Select Multi Display Mode dialog box select all the seven spectra, starting with the reference spectrum. Click on the OK button to close the dialog box and initialize the multiple display. Click on the File Param. button and inspect the... 

Scaling buttons In the Contour mode 2 increases and /2 decreases, the vertical scaling of both the projections and of the contours by a factor of 2. To individually scale only the projection or only the contours, use the menu item Select in the Layout submenu of the Display pull-down menu. 

Use the same 2D spectrum to try out the other types of projections. From the Display pull-down menu choose the Layout menu and select Slice to interactively inspect slices along Fl and F2 and to define a suitable pair as projections. Do the same with the Slice numerical option. 

Use again the same 2D spectrum and from the Display pull-down menu choose the Resolution... option. Reduce the resolution to 128x128 and load the 2D file again to make the size reduction current. The display build-up will be faster, but the resolution is obviously worse. 

Use the same 2D spectrum to become familiar with all the Window options available in the Display pull-down menu. Display the full 2D spectrum at normal size (512x512). Click on the Create button and in an empty part of the display create a window. Now select a region you want to expand and copy it into the newly created window. Create a second window and expand a second part of your 2D spectrum. Use the Help tool for further information on how to do this and to display the axis within these windows. 

From the Display pull-down menu choose the Window option and create an additional window within the 2D plot to include the structural formula of glucose. Start a parallel ID WIN-NMR session and load the structure file D NMRDATA GLUCOSE GLUCOSE.WMF) into the ID WIN-NMR Preview window. Copy it into the clipboard with the Copy command in the Edit pulldown menu of ID WIN-NMR. Return to 2D WIN-NMR, activate the additional window and choose the Paste option in the Output pull-down menu. Move the mouse cursor into the additional window and initialize the transfer from the clipboard by clicking the left mouse button. Resize this window if necessary. 

Adding or subtracting FIDs is only possible with 1D WIN-NMR and is accomplished with the File Algebra option in the Process pull-down menu. A dialog box allows you to select the second file and to specify whether FIDs or spectra should be added/subtracted. At the same time the screen is horizontally split into three regions with the original spectrum at the top, the second spectrum in the middle and the result of the arithmetic operation at the bottom. A new button panel appears where several specific options are available (Fig. 5.27). In contrast to the Dual Display function, available in the Display pull-down menu and discussed in chapter 4, more options exist with File Algebra, i.e. to store the result or to move one of the traces with respect to the other. Use the Help tool for more information. 

In many of the Check its in this book different spectra are compared using the Dual and Multiple Display modes which are selected from the Display pull-down menu. This pull-down menu contains a number of different options for changing colours, fonts and miscellaneous display parameters, most are mostly self explanatory [3.2]. Although in the dialog boxes associated with both display modes it is possible to toggle the selection between FID and Spectrum, in the following discussion it is assumed that only spectra are to be displayed.
