Geometricus Represents Protein Structures as Shape-mers derived from Moment Invariants

A structure-based, alignment-free embedding approach for proteins. Can be used as input to machine learning algorithms.

See the documentation.

Installation

Geometricus is a Python (3.9+) package with NumPy, SciPy, Numba, PyTorch and ProDy as dependencies.

Install with pip install git+https://github.com/TurtleTools/geometricus.git

Usage

See the Getting Started page for example usage.
