Re: [PyMOL] arbitrary distance label for atom pair

[Jason V. <jas...@sc...>]

Richard,

The PyMOL team was just discussing this a few days back. Sadly, there
is no way to do this using standard labels.

If you have Incentive PyMOL v1.7 you can use the new callout command
(http://pymol.org/dsc/dokuwiki/doku.php?id=command:callout). Otherwise
you can use the pseudoatom
(http://www.pymolwiki.org/index.php/Pseudoatom) as a label:

# create a single ala

frag ala

# create a labeled distance

dist 2/N, 2/O

# hide the labels

hide labels

# create a new label at the center of the selection

pseudoatom new_label, (2/N or 2/O), label="Some arbitrary label here: \316\261"

orient


Cheers,

-- Jason
