Text Annotation

NO — Notes subroutine

This allows the user to define multiple text boxes to be displayed with the spectrum. NO enters the subroutine.

To create a “note”, type A. This brings up the dialog box below, allowing the user to enter desired text. Text can be multiple lines. By default, this Note is positioned in the upper left corner of the screen. Alternatively, a Note can be created at the position of the mouse cursor by clicking the right mouse button.

There are 2 ways Notes can be positioned:

One option is to display the Note at a fixed position on the screen, meaning that it remains visible and at a fixed position regardless of whether the full spectrum is displayed, or an expanded region of the spectrum. Use this for text such as sample name or acquisition parameters, that should be visible regardless of how much of the spectrum is currently displayed.

Alternately, a Note can be locked to (associated with) a specific data point of the spectrum. In this case, if the spectrum is expanded so the corresponding data point is not displayed, the Note will also not be displayed. Use this for text related to a specific peak or region of the spectrum, such as peak assignments.

The option of locking each note to a data point can be set from within the Note editor dialog box, from the Edit menu or by keyboard commands L (lock) and U (unlock).

Once a Note has been created, it can be moved by dragging with the left mouse button (place the mouse cursor within the box containing the Note, press and hold the left mouse button, and drag). If the Note is locked to a data point, its vertical position can be changed this way, but not its horizontal position. If the Note is not locked, it can be moved anywhere on the screen.

Additional notes are added in the same manner. The current Note is indicated in green. The current Note can be edited with the E subcommand. To select a different Note as the current Note, the left and right arrow keys will step through the list of Notes.

The note box cannot be resized; its size is determined by its contents.

Notes containing peak frequency information can be created from the Base Level of the program using the cursor — see description.

If more than one Note is created, only one at a time is designated as the “Current Note”. The current note is always shown with its box drawn in red, while all others are green. A different Note can be selected as the Current Note by placing the cursor within its box and clicking with the left mouse button. Alternatively, it is possible to step through the list of Notes using the left and right arrow keys, in the order the Notes were created.

A Note can be created containing acquisition parameters using the P subcommand. For example,

5.4mg_of_Codeine_in_CDCl3 File Name: cod-1h.nmr User: DJB Date: Dec 28, 2004 00:25:38 Solvent: CHLOROFORM-D Experiment: single_pulse.ex2 SF: 399.782196 SW: 15192.950195 PW: 6.800000 RD: 0.900000 Acquisition time: 4.313580 NA: 16 Size: 65536

By default, this note is locked to the a position near the upper left corner of the screen, so it is displayed regardless of how much of the spectrum is displayed. This note can also be created from the program’s base level using the LP command.

There are several operations that apply only to the Current Note:

E to edit the Note’s text
F to set the font properties for that Note
D to delete the Note

All notes can be cleared by typing C or from the Edit menu.

Display of all Notes while outside the Notes subroutine is turned on and off with Notes sub-commands S and N (Show or No-Show) or from the View menu.

Notes are saved in the data file header, and later read when the file is opened.


A — Add new notes box
C — Clear all notes boxes
D — Delete current Note
E — Edit current Note
F — Choose font for the current Note
L — Lock the current Note to a data point
N — Display of Notes outside the subroutine is turned off
P — Create a Note showing acquisition parameters
S — Show Notes while outside the Notes subroutine
U — Unlock the current note from its data point, so it remains at a fixed screen position
<Enter> to exit the subroutine
