Calculate structural representations (dihedral angles, CA pairwise distances, and strain analysis) for downstream analysis (e.g., PCA, t-SNE, or UMAP)

Project description

colav

colav (Conformational Landscape Visualization) provides tools for representing protein structures and mapping conformational landscapes.

colav supports calculations for dihedral angles, pairwise distances, and strain. It is built on biopandas, NumPy, and SciPy. The methods analyze PDB files, either one-by-one or all together. The three methods currently implemented are:

Installation

You can install colav using pip:

pip install colav
