Our small molecule lab and molecular observatory at Caltech is starting to use Chimera and I think small molecule crystallography labs in general would use Chimera more if this feature were available. I do have to admit that I am interested in this feature for selfish reasons. I am using Chimera for several publications and for the graphics in my thesis which, has to be finished in the next couple of weeks, and I would really like to use this feature. </div></div></blockquote><br></div><div>Hi Dave,</div><div><span class="Apple-tab-span" style="white-space:pre"> </span>Yes, reading/preserving the ANISOU info lays the groundwork for eventually showing anisotropic ellipsoids. There's still a lot of work to go before showing the ellipsoids becomes a usable feature of Chimera. It might make it into our next release (middle of next year) and it might not. As a stopgap, I've attached a script that will show ellipsoids for any currently selected atoms. You can run it by simply using File->Open or the "open" command. The first two lines of the script control the size and color of the ellipsoids, so change them if you like. The script leverages some code that Tom Goddard wrote for showing principal axes of inertia as an ellipsoid.<br></div><span class="Apple-tab-span" style="white-space:pre"> </span>Good luck with the thesis!<br><div><br></div><div>--Eric</div><div><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><font face="Helvetica" size="5" style="font: normal normal normal 16px/normal Helvetica; "><br class="Apple-interchange-newline"> Eric Pettersen</font></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><font face="Helvetica" size="5" style="font: normal normal normal 16px/normal Helvetica; "> UCSF Computer Graphics Lab</font></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><font face="Helvetica" size="5" style="font: normal normal normal 16px/normal Helvetica; "> <a href="http://www.cgl.ucsf.edu">http://www.cgl.ucsf.edu</a></font></div></div></div><br><div></div><div></div></body></html>
