Custom Residue Labeling

Choosing Actions... Label... residue... custom... from the Chimera menu opens the dialog for custom residue labeling.

The Residue label field contains substitution codes and arbitrary text representing the composition of the label. A substitution code is of the form %(descriptor)s where descriptor can be any of the following:

name - residue name
1-letter code - one-letter residue code for standard amino acids, residue name for other residues
specifier - residue number, insertion code, and chain ID
number - residue number
insertion code - residue insertion code
chain - chain ID

or the name of any residue attribute. Clicking the button for a descriptor inserts its substitution code at the current cursor position in the Residue label field. Arbitrary text, including spaces, can be entered before, after, and between substitution codes, and substitution codes can be entered manually.

The following would label lysine, residue 8 in chain C as "wt K8":

wt %(1-letter code)s%(number)s

If the custom label definition includes a descriptor that is not applicable to a particular residue (not all residues have an insertion code or chain ID, for example), nothing will be inserted in that part of the label for that residue.

OK performs the labeling and dismisses the dialog, whereas Apply performs the labeling without dismissing the dialog. Close simply dismisses the dialog. Help opens this manual page in a browser window.
