====== Structure Solution ====== There are lots of different structure solution methods built in to Topas. Some places to look for information include: * The topas user manual * Sections of the Technical Reference * John's [[http://community.dur.ac.uk/john.evans/topas_workshop/topas_user_menu.htm|on line tutorials]] * Input files in the Examples/Structure solution menus in jEdit * Input files in the Examples/Charge-Flipping menus in jEdit Martin Fisch has provided a fully worked example on the structure solution of urea which you can download as a {{:urea.zip|.zip file}}. This tutorial goes through all the steps from indexing a pattern, improving the unit cell, solving the structure by simulated annealing and structure refinement.
