Dear all,
A couple of questions regarding twinning:
1. The structure I work with has multiple twinning domains
(4 to be exact, with pseudo-orthorhombic 222 symmetry
induced by twinning in P1). I feed the autobuild script the
operators using a keyord:
input_files.refine_eff_file_list=mytwinrefinement.eff
(see attached file) but only the last one seems to be used.
Do I guess correctly that there is only provision for two domains
adn therefore the last twinning definition overrides any
previously defined one?
If so, is there a way of specifying and using multiple
twinning domains/operators?
2. Output structure factor amplitudes: are they
detwinned? Are they detwinned before the density modification
in resolve? and during it?
Thanks for any clarification/suggestions
Regards
Pietro
