Properties
==========

The core of ProteoTwirl is angle-dependent property calculation. ProteoTwirl 
contains three different types of propertes, although custom types can easily 
be added. 

- (1) **Count Properties** : These assign some value to each atom or residue and then aggregate (mean/sum/max/...) those values to create a value for a given angle. These generally require some ``Selector`` to be useful, as otherwise all angle will be the same value from aggregation of across all atoms. 

- (2) **Shapes** : Shapes are properties that produce the shape of a set of atoms when viewed from a given angle. These are covered in detail in :ref:`shapes`. 

- (3) **Shape Properties** : These are properties of shapes, such as their area, and require that a shape has already been calculated for the system in question
