+Detection of Protein Symmetry  and Pseudo-symmetry using BioJava
+================================================================
+
+This chapter is still under construction. See the [protein symmetry](https://github.com/rcsb/symmetry) project for more information for now.
+
+BioJava can be used to
+
+> Detect, analyze, and visualize **protein symmetry**
+ - Detect symmetry in **biological assemblies**
+ 
+![PDB ID 1G63](https://raw.github.com/rcsb/symmetry/master/docu/img/1G63.jpg)
+
+- Detect **internal pseudo-symmetry** in protein chains
+ - Visualize results in [Jmol](http://www.jmol.org)
