<div dir="ltr">I have data from a crystal with anisotropic diffraction. After scaling and merging using the webserver staraniso, I would like to refine using phenix refine. Could you tell me if phenixrefine will try to fill in the missing reflections that were removed in the staraniso procedure? If so, is there a a way to prevent this fill in? Following is the warning message for the Staraniso server:<br><div><br><br clear="all">We are
grateful to Andrew Leslie (MRC-LMB) for identifying a potentially
undesirable 'feature' of CCP4/REFMAC (and possibly other refinement
software), namely the 'fill-in' of unobserved data with <i>DF</i>calc
which makes it effectively <i>incompatible</i> with the MTZ file output
by STARANISO. Our advice is therefore to use <b><a target="_blank" href="http://www.globalphasing.com/buster">BUSTER</a></b> for refinement
using the downloaded MTZ file, unless the user can find a way to disable
that feature in the alternative software.
<p>In general, any treatment of STARANISO's output data that adds
missing reflections out to the resolution limit may result in a very
high proportion of unobserved data compared with data that have had a
cut-off applied according to an isotropic criterion. Where missing
reflections have been added in this way the user should take care to
verify that any applications used to process the data subsequently can
handle it correctly.
