Calculate Root-mean-square deviation (RMSD) of two molecules, using rotation, in xyz or pdb format
Python 3 script for overlaying or superimposing two or more molecules. The overlayed / superimposed molecules can be displayed and the modified coordinates can be saved as xyz files. Coloring by atom or molecule is possible.
Kabsch algorithm for optimally aligning two paired sets of points
Calculate and apply the optimal transformation matrix that minimizes the RMSD (root mean squared deviation) between two paired sets of points.
Differentiable, gradient-safe Kabsch (SVD) and Horn (quaternion) point-cloud alignment across NumPy, PyTorch, JAX, TensorFlow, and MLX.
A simple library to compute rigid transformation matrix between two point sets.
RNA structural alignment via multi-strategy TM-score optimization. Finds higher-scoring superpositions than USalign on 66% of pairs.
