Tip
Check out pyscal3, a completely new pyscal which is faster and can handle a large number of atoms, with a much more user-friendly interface. This repository will continue receiving bug fixes, including any new raised issue. It will also be tested for new python versions. However, new features will only be added to pyscal3.
Complete documentation with examples available here.
pyscal is a python module for the calculation of local atomic structural environments including Steinhardt's bond orientational order parameters during post-processing of atomistic simulation data. The core functionality of pyscal is written in C++ with python wrappers using pybind11 which allows for fast calculations with possibilities for easy expansion in python.
Steinhardt's order parameters are widely used for identification of crystal structures. They are also used to identify if an atom is solid or liquid.
pyscal can be installed directly using conda by the following statement-
conda install -c conda-forge pyscal
From repository
pyscal can be built from the repository by-
git clone https://github.com/pyscal/pyscal.git
cd pyscal
python setup.py install --user
