It seems that the problem are the double bonds. Cholesterol is done very nicely! I've set up a test page at http://biomodel.uah.es/Jmol/minimize/minimize.htm - Check out the new SourceForge.net Marketplace. It's the best

I'm guessing that the UFF forcefield is more tuned to getting energies right than structure. If that's the case, it may take some tweaking, and we may want to implement some alternative parameterizations that stiffen the structure (at the expense of energy). Or there could be a bug Bob

Angel, There problem was with the torsional calculation. I've uploaded a modified jar files. -- see http://chemapps.stolaf.edu/jmol/docs/examples-11/new.htm That thyroxine.cml minimizes just fine now. Developers, I had some very strange cross-SVN branch thing going on there. A few files in

Wonderful, Bob! The newest applet is working very well. Something funny but very sound: go to http://biomodel/Jmol/minimize/minimize.htm Load the 2D caffeine, then click minimize several times until it stabilizes; note the sp3 nitrogens Now click on recalculate aromaticity and repeat several

Nico, you can release 11.5.21. All, I don't have time today to go over the details, because I'm running out of town in 5 minutes. Thanks to Tim Vandermeersch and Geoff Hutchison for their generous contribution to Jmol of a minimizer for the UFF force field. This added a new Jar file to the
