<p>Hi Phenix users,</p>
<p>since I had to answer this very same question off-list three
times in past 48 hours, I thought I post this for future
reference...</p>
<p>Yes, thanks <b>Billy</b> there is a GUI for
phenix.real_space_refine (tool to refine atomic models against
maps, such as cryo-EM maps)! To give it a try, you need:</p>
<p>1) Get the latest nightly build, dev-2427 for instance:</p>
<p><a class="moz-txt-link-freetext" href="http://phenix-online.org/download/nightly_builds.cgi">http://phenix-online.org/download/nightly_builds.cgi</a></p>
<p>2) Enable alpha-test programs in Phenix GUI. To do this:</p>
<p> -- start Phenix GUI;</p>
<p> -- go to Preferences and tick "Enable alpha-test programs and
features" box;</p>
<p> -- restart the GUI (close down, then start again);</p>
<p> -- phenix.real_space_refine will be available in Refinement
section on the right (Real-space refinement [alpha]).</p>
<p>Note, it has a very handy feature to see/explore/edit
secondary-structure restraints graphically.</p>
<p>Also note that <b>this is alpha-test version meaning that
glitches are not unexpected</b>! However your feedback will help
to improve it, so please let us know should you encounter
problems, have suggestions or found bug(s)!</p>
<p>All the best,</p>
<p>Pavel</p>
