A tool to characterize the local structure of liquid water by geometric order parameters.

Getting started

Installation:

$ pip install iorder

or

$ git clone https://github.com/ipudu/order
$ cd order
$ python setup.py install

Running:

# calculate bar parmeter for center atom of O
$ order foo.xyz -t bar -c 'O' -f 100 -b 100

Feature Support

Order is ready to calculate several geometric order parameters:

• Orientational Tetrahedral Order
• Translational Tetrahedral Order
• Asphericity of the Voronoi Cell
• Ionic Conductivity
• and more

Documentation

The documentation of Order is available at http://order.readthedocs.io/.
