+To qualitatively reproduce the default StructuralDB in ProMod3, you first 
+perform step 1 and 2 with a non redundant set of protein structures as 
+defined by PISCES with around 25000 chains (e.g. seq id threshold: 90, 
+resolution threshold: 2.2). 
+Repeat step 1 and 2 with a smaller PISCES list (5000-6000 entries, 
+e.g. seq id threshold: 25 , resolution threshold: 1.8). 
+The first database serves as default StructureDB and the second db as 
+the source db for the structural profiles generated in steps 3-5.
