Overview

stko-lite is a light-weight version of stko with mostly the same functionality.

stko is a Python library for performing optimizations and calculations on complex molecules built using stk. In the case of optimizations, a clone of stk.Molecule is returned. For calculators, a Results class are used to calculate and extract properties of an stk.Molecule. There is a Discord server for stk, which can be joined through https://discord.gg/zbCUzuxe2B.
