Dear list,

another question related to stereochemistry, but concerning coot.
When using the RSR zone button, which should "improve geometry and fit to
map", it seems that the geometry is not always improved : some chiral
centers can be inverted. The surprising thing is that using the "regularize
zone" afterwards does not correct this, even if the chirality of the center
is not set to both, but to positive in the cif dictionnary (ie should define
only one possible chirality).
Has anybody else notices this behavior ? Is there a way to adjust the weight
between geometru and map terms in the RSR option ?

thanks for any ideas or advices

laurent
