: A Python Package for Polymer Chain Orientation and Microstructure Evolution Monitoring.

In the pursuit of informing experimental techniques with in silico optimizations, we propose a pip deployable Python package, , to easily determine polymer crystallites within molecular dynamic melts and the chain orientation parameters of atomistic and coarse-grained simulations. The package supports the commonly used ⟨⟩, ⟨⟩, and ⟨⟩ order parameters based on the chain chord vector and utilizes a modified DBSCAN algorithm to determine crystalline regions. The results of analysis are written to text and LAMMPS dump files for visualization and analysis.
