Here is an example:
action = *add delete change
atom_selection_1 = chain A and resname HEM and resid 154 and name FE
atom_selection_2 = chain A and resname MTO and resid 155 and name O
symmetry_operation = -x,y,-z
distance_ideal = 2.2
sigma = 0.01
To get the symmetry_operation, you can either use Coot (turn on drawing on
symmetry copies, then click on the copy and look for the symmetry operation
in the status bar), or run this command:
iotbx.show_distances your.pdb > all_distances
This will give you a long all_distances file, but if you look for "sym="
hopefully there will only be a few matches.
