Okay, finally writing documentation now. Sorry! There isn't actually a
method for combining rigid body refinement with secondary structure
information yet; it would probably be a day or two of work for Pavel or me.
However, the "morph" option on AutoBuild may do a better job at moving
pieces of that size into place. (And there are probably other programs
which I haven't used that do something similar.)
You can use the secondary structure restraints with simple coordinate
refinement (strategy individual_sites), by adding
"main.secondary_structure_restraints=True" to the command-line (there is a
corresponding button in the GUI, but only if you have the alpha-test mode
turned on). Everything else is (in theory) automatic, but if you aren't
using hydrogens, add "h_bond_restraints.substitute_n_for_h=True" as well,
just to be safe.
