hello,

What is the best way to selectively remove bond length restraints on some selected atoms for phenix.refine?
i found the commands for a .param file:

refinement {
geometry_restraints.remove {
    angles = None
    dihedrals = None
    chiralities = None
    planarities = None
}
}

but no bond length command in the manual online. http://www.phenix-online.org/version_docs/dev-283/refinement.htm
otherwise there is the commands

refinement {
geometry_restraints.edit {
    bond {
    action= *delete change
    atom_selection_1= (selection1 here)
    atom_selection_2= (selection2 here)
    distance_ideal= None
    }
}
}

is it a good way to deal with the problem ?
thanks in advance for your help.

Maxime
