Coordinates symmetry is “dynamic”. Symmetry atoms can be labeled 1. Every time you recentre, the symmetry coordinates are updated. The information shown contains the atom information and the symmetry operation number and translations needed to generate the atom in that position.
By default symmetry atoms are not displayed.
If you want coot to display symmetry coordinates without having to use the gui, add to your ~/.coot the following:
(set-show-symmetry-master 1)
The symmetry can be represented as C\alphas. This along with representation of the molecule as C\alphas (Section Display Manager) allow the production of a packing diagram.
Sometimes (rarely) coot misses symmetry-related molecules that should be displayed. In that case you need to expand the shift search (the default is 1):
(set-symmetry-shift-search-size 2)
This is a hack, until the symmetry search algorithm is improved.
[1] symmetry labels are in pale blue and also provide the symmetry operator number and the translations along the a, b and c axes.
