pyscal — python Structural Environment Calculator
Complete documentation with examples available here.
What changed in version 4
pyscal grew over the years from a small wrapper around a few C++ routines into a full structural-analysis toolkit. With each addition the original System / Atoms object model became more rigid: every new descriptor had to be threaded through the same class hierarchy, neighbor lists were tied to a particular System instance, and interoperating with the rest of the atomistic-simulation Python ecosystem (ASE, pymatgen, OVITO, LAMMPS dump readers) required converting back and forth between formats.
Version 4 is a ground-up rewrite around two ideas:
-
ASE
Atomsis the data structure. pyscal no longer ships its own atoms class. Anyase.Atomsobject — read from a LAMMPS dump, a POSCAR, a CIF, an XYZ, built withase.build.bulk, or constructed by hand — can be passed directly to a pyscal function. Results are written back asatoms.arrays["pyscal_*"]for per-atom quantities andatoms.info["pyscal_*"]for global ones, so they travel with the atoms object and remain accessible to the rest of the ASE ecosystem. -
Functional API. Every descriptor is a top-level function in
pyscalthat takes anAtomsobject as its first argument. Neighbor lists are computed once withpyscal.find_neighbors(atoms, ...)and reused by every subsequent descriptor. There is no system state to keep in sync, no method-chaining order to remember, and no class to subclass when adding a new descriptor.
The C++ core is unchanged in spirit — voro++ for tessellation, hand-written kernels for Steinhardt-type invariants, pybind11 bindings — but is now exposed through a much thinner Python layer.
A typical session looks like:
import pyscal
from ase.build import bulk
atoms = bulk("Cu", "fcc", cubic=True).repeat(4)
pyscal.find_neighbors(atoms, method="cutoff", cutoff=0) # adaptive
q4, q6 = pyscal.steinhardt_parameter(atoms, l=[4, 6])
labels, names = pyscal.identify_ackland_jones(atoms)
print(atoms.arrays["pyscal_q6"].mean()) # ≈ 0.57 for fcc
What is included
This release consolidates a number of new descriptors alongside the existing ones:
- Neighbors — fixed cutoff, adaptive cutoff, SANN, Voronoi
- Steinhardt $q_l$ and averaged $\bar{q}_l$
- Wigner $W_l$ — third-order rotational invariants for distinguishing cubic structures
- Minkowski structure metrics — Voronoi-area-weighted, parameter-free $q_l$
- Solid/liquid classification and clustering
- Disorder parameter
- Angular and $\chi$ parameters; Ackland-Jones structural classifier
- Coordination measures — coordination number, effective coordination, generalised coordination, local density
- Angular distribution function and bond-length distribution function
- Voronoi tessellation — structural vector and Voronoi volume
- Centrosymmetry parameter
- Common neighbor analysis (CNA, adaptive CNA, diamond variants)
- Entropy parameter (Piaggi–Parrinello)
- Warren–Cowley short-range order
- Atomic deformation — strain tensor, von Mises invariant, $D^2_{\min}$, slip vector
- Wigner–Seitz defect analysis — vacancies, interstitials, antisites against a reference
- Atomic Cluster Expansion (ACE) descriptors up to body order four
A complete list with mathematical definitions and example notebooks is available in the documentation.
Installation
pyscal is distributed on PyPI and conda-forge as pyscal3 (the name pyscal on PyPI refers to a separate, unrelated package). After installation, both import pyscal and import pyscal3 work.
From conda-forge:
conda install -c conda-forge pyscal3
or from PyPI:
pip install pyscal3
To build from source:
git clone https://github.com/pyscal/pyscal3.git
cd pyscal3
pip install .
A C++ compiler with C++17 support is required when building from source.
