SPECTRAL DISPLAY MENU

Hold down MENU within a spectral display window to display this menu
Attributes
This command will open up the spectral attributes window. If the window is already open it will set it to display the attributes for the active spectral window.
View
The commands in this menu allow the user to change the region of the spectrum that is displayed in this window.
Draw
Draw the current view.
Expand
This command changes the plot limits to include the region bounded by the two crosshairs and redraws the spectrum.
Previous
This command changes the plot limits to that which was active prior to the last expansion and redraws the spectrum. The previous 8 views are saved so the user can return to them with this command.
Full
This command changes the plot limits to that of full spectral width for each of the two displayed dimensions and redraws the spectrum.
Center
Center the current view on the crosshair cursor (number 1).
Swap
This command exchanges the view limits for the two displayed dimensions and redraws the spectrum. The result is to display the view across the diagonal from the current view. This command is only appropriate for 2D homonuclear spectra
Edit
This menu provides commands to copy display attributes from one window to another.
Copy
This command saves the display attributes of the current window into the copy buffer.
Paste
This command sets the display attributes of the current window to those in the copy buffer.

The selected entry in this menu determines whether or not contour data is read from the matrix or a contour file..
Live
Data for the contour plot is obtained from the matrix file.
Record
Data for the contour plot is obtained from the matrix file, but the contours are recorded in a file for future playback. Only those planes that are actually drawn while in this mode are recorded.
Play
Data for the contour plot is obtained from the contour file that was created in record mode.
Misc.
Various items are controlled from this menu.
AutoClear
If this item is active (the default), the spectral display window will be cleared prior to the display of the contour plot. If inactive, the next contour plot will overlay the current plot.
Reset
Select this entry to reset the displayed attributes to the windows current values.

The next region of the panel provides three text boxes to specify the contour level, the ratio between subsequent contours, and the number of contour levels to draw.

Level
Type an entry in this box to specify the level at which contours are to be drawn. This value is multiplied by a global scale paramter (set in the usprefs dialog, default 1e6) to generate the actual value that is used. The up and down arrows provide a convenient means to increment or decrement the contour level. Clicking on the up arrow raises the contour level to a value equal to the current level times the current value of the multiplier (the value in the next field). Clicking on the down arrow lowers the contour level to a value equal to the current level divided by the current value of the multiplier (the value in the next field).
Scale
Type an entry in this box to specify the scale value at which 1D slices are to be drawn. This value is multiplied by a global scale paramter (set in the usprefs dialog, default 1e6) to generate the actual value that is used. The up and down arrows provide a convenient means to increment or decrement the scale level. Clicking on the up arrow raises the scale level to a value equal to the current level times the current value of the multiplier (the value in the next field). Clicking on the down arrow lowers the scale level to a value equal to the current level divided by the current value of the multiplier (the value in the next field). Whenever the Level value is changed the Scale value is changed to be 10.0 times the Level value as this generally provides good results.
Mul
Select a value using the slider to specify the ratio between subsequent contour levels. For example, a value of 1.5 means that each contour will be 1.5 times as high as the previous one.
NLvl
Select a value using the slider to specify the maximum number of contours to be drawn.
Xoff
Select a value using the slider to specify the offset position(from 0.0 to 1.0) at which X (and Z) slices are drawn. be drawn.
Yoff
Select a value using the slider to specify the offset position(from 0.0 to 1.0) at which Y (and Z2) slices are drawn. be drawn.

The next section of the panel controls the plot limits.

X
Enter values in the next two text fields to set the plot limits (in ppm) for the x (horizontal) axis. If the entry is followed (without an intervening space) by a "p", then the value is considered to be in units of points of the dataset. The minimum and maximum plot limits can be entered in either order. These values are automatically set to give the full spectrum when a new dataset is assigned to this window.

The text in the third field is used as a label for the x (horizontal) axis. This value is used to label the axis on hard copy plots, is used for determining the correlation of cursors between different windows (see cursors, below), and is used during peak-picking and peak display (see Peak Picking, below). This is automatically set to the value assigned to the corresponding dimension (see below) during the referencing of the matrix, but can be changed by entering a new value in this field.

1(2,3,4) Hold down MENU over this item to select the dimension of the matrix to be displayed on the xaxis.

Y
Enter values in the next two text fields to set the plot limits (in ppm) for the y (horizontal) axis. If the entry is followed (without an intervening space) by a "p", then the value is considered to be in units of points of the dataset. The minimum and maximum plot limits can be entered in either order. These values are automatically set to give the full spectrum when a new dataset is assigned to this window.

The text in the third field is used as a label for the y (vertical) axis. This value is used to label the axis on hard copy plots, is used for determining the correlation of cursors between different windows (see cursors, below), and is used during peak-picking and peak display (see Peak Picking, below). This is automatically set to the value assigned to the corresponding dimension (see below) during the referencing of the matrix. 1(2,3,4) Hold down MENU over this item to select the dimension of the matrix to be displayed on y axis. 1(2,3,4) Hold down MENU over this item to select a second dimension of the matrix to be displayed on the y axis. If this value is not 0, the resulting contour plot will consist of a diagonal plane through the spectrum. The size (in data points) of the two dimensions applied to the single axis must be the same for this to work. This is generally only appropriate to homonuclear 3D spectra. THIS FEATURE IS NOT CURRENTLY ACTIVE.

Z
Enter values in the next two text fields to set the plot limits (in ppm) for the z (3rd Dimension) axis. If the entry is followed (without an intervening space) by a "p", then the value is considered to be in units of points of the dataset. The minimum and maximum plot limits can be entered in either order. These values are automatically set to display the first plane when a new dataset is assigned to this window. The spectral display window will be cleared prior to drawing the first plane (if AUTOCLEAR) is set. Subsequent planes will be overlaid on top of the first plane. To draw a single plane, set both values equal to each other.
Z2
Enter values in the next two text fields to set the plot limits (in ppm) for the z2 (4th Dimension) axis. If the entry is followed (without an intervening space) by a "p", then the value is considered to be in units of points of the dataset. The minimum and maximum plot limits can be entered in either order. These values are automatically set to display the first plane when a new dataset is assigned to this window. The spectral display window will be cleared prior to drawing the first plane (if AUTOCLEAR) is set. Subsequent planes will be overlaid on top of the first plane. To draw a single plane, set both values equal to each other.

SELECT DATASET

Before drawing a spectrum you must associate a particular dataset with the spectral window. To do this choose "Dataset" from the "Files" menu of the Spectral Attributes Panel. This brings up the following panel. Alternatively, you can use the win -dataset command.

The panel lists all datasets that have been opened.

OK
Associate the selected dataset with the spectral window. The panel is then closed.
Cancel
Close this panel without specifying a dataset for the spectral window..

PEAK ATTRIBUTES PANEL

This panel provides controls to specify the display of peaks in the spectral windows. The window header will indicate the name of the window whose attributes are being set, and the name of the dataset currently assigned to the window. The panel is displayed by selecting the Attributes option of the Peak Menu in the Spectral Display Menu.

Col On
A pull-down menu of colors. If colortype is set to "plane",this specifies the color of peaks that are within the range of displayed planes. This mode is only applicable to three or four dimensional spectra. If colortype is set to "assigned", this specifies the color of peaks that have been assigned to specific atoms.
Col Off
A pull-down menu of colors. If colortype is set to "plane",this specifies the color of peaks that are not within the range of displayed planes, but are no more than "offset" number of planes outside this range. This mode is only applicable to three or four dimensional spectra. If colortype is set to "assigned", this specifies the color of peaks that have not been assigned to specific atoms.
Col Type
Specifies how the color of peaks is determined.
Plane
Color is determined by whether or not peaks are within the range of displayed planes.
Assigned
Color is determined by whether or not peaks have been assigned to specific atoms.
Error
Color is determined by the value of the Error field for the peak. If any dimension has a value not equal to "++" then the peak is drawn in the "Col Off" color.
Lab Type
Specifies how the label displayed with each peak is determined.
Number
The label is the peak number.
Label
The label is composed of the assignment labels for each peak dimension.
Residue
The label is composed of the unique residue numbers from the assignment label for each peak dimension.
Atom
The label is composed of the atom fields from the assignment label for each peak dimension.
Dis Type
Specifies how the peak is displayed.
Box
The peak is drawn has a box centered on the peak position, with a width equal to the peak bounds. A label is placed at the corner.
Simulated
The peak is drawn with simulated contours. The intensity and linewidth for the simulation are taken from the peak intensity and width.
Label
The peak position is labelled, but a box is not drawn.
Offset
Peaks are displayed that are within this number of planes of the range of planes that are displayed (for three and four dimensional spectra). For example, if planes 17 to 18 are currently being displayed in the spectral window, any peak that was closest to planes 17 to 18 would displayed, with the color selected in the "Col On" menu. Any peaks closest to planes 13 to 16 or 19 to 22 would be displayed with the color selected in the "Col Off" menu. Peaks outside of this range of planes would not be displayed.
Show Peaks Menu
This menu controls the response of the spectral window to actions taken in the peak analysis window.
None
If this item is selected, no action will occur in this window in response to peak selections in the peak analysis window.
Expand
If this item is selected an expansion of the spectrum around a particular peak will appear when a peak is selected in the Peak Analysis window. The width of the display region around the peak will be automatically set to five times the peak width in each of the display dimensions.
ExpandFixed
If this item is selected an expansion of the spectrum around a particular peak will appear when a peak is selected in the Peak Analysis window. The display limits will be changed so that they are centered on the new peak, but the width of the display region will not change from the current values.
Plane
If this item is selected the spectrum will be plotted at the particular plane(s) corresponding to the peak selected in the Peak Analysis window. The x and y plot limits will not change from the current values.
Links
If this is selected then peaks that have "links" between them will be drawn with a line connecting them.
Display Peaks Menu
This menu controls whether or not peak boxes and labels are drawn in the spectral window when the spectrum is redrawn. Hold down MENU to select a peak list to be displayed in the window. Peak boxes or simulations will be drawn for any peaks from the selected peaklist that are within the limits of the window, whenever the contour plot is displayed.
