Delete All Labels:

This deletes all labels. This is helpful if you've labeled too many atoms and want to start from scratch.

Global Offset (apple-G):

Simple routine. Allows the user to offset all of the labels in the X and Y directions. Just input the offset (in pixels) in the dialog box and hit O.K. As with other label offsets, these adjustments are cleared after any rotations are performed.

Reset Label Offsets (apple-R):

Erases all label offsets. After selection the labels are moved to right of the atoms.

Create Labels:

Allows the user to create the exact type of label to be applied to the atoms. Each atom has a residue type, residue number, and atom type identifier. To create a type of label, just select them in the order you wish them to appear. You do not have to use all three atom identifiers for the labels. To help you, I have changed the buttons over the various labels upon selection. For example, say that you decided that the residue type is the first thing to appear in the label. You click on the button above the label saying 'Residue Type' and the button will change to read 'Item #1'. If you make a mistake, just hit the 'Start over' button and do it again. Every time you enter this routine, I have to purge the memory that these labels reside in. Therefore, each time you enter this subroutine, you loose the label that you chose before. However, the atoms that you selected are still flagged for being labeled with the new label.

Font:

The program goes to the System file and finds all available Fonts. These fonts are displayed as a pop-menu. The selected font will be used for all subsequent labeling.

Style:

The user is allowed to change the style of all labeling with this pop-up menu. Each menu item is drawn with that particular style.

Size:

The user can change the label font size to one of the standard sizes shown in the pop-up menu or some other size by selecting 'other...'.
