Hi Tim,<br>
<br>
it is a shame that I can't remember that particular paper where I
think Randy Read or Axel Brunger have demonstrated that phase error
and Rfree are well correlated. So if you get best Rwork and Rfree
chances are you also get best map too.<br>
<br>
All the best,<br>

<pre wrap="">Dear George,
what are the reasons why are you trying to reduce the R/Rfree instead of
producing the best possible map?
Best,
Tim

<pre wrap="">Hi Phenix users,
I was looking at the phenix-refine manual and it mentions running
optimize_mask=true
optimize_xyz_weight=true
optimize_adp_weight=true
I was wondering what else I could try to bring the Rw/Rf down by 1-2%
if possible, just wondering if there are any other strategies I could
try.
Thank you,
George
