Area of Science:

Computational Chemistry
Molecular Dynamics
Biophysics

Background:

Analyzing molecular transition pathways is crucial for understanding mechanisms.
Pathway diversity and variable lengths pose significant analytical challenges.
Existing simulation methods require robust tools for pathway analysis.

Approach:

Introduced LPATH, a Python tool for linguistics-assisted pathway clustering.
Developed a semi-automated method involving state discretization, text-string sequence extraction, and similarity scoring.
Implemented a machine learning-based two-stage method to manage memory constraints during state clustering.

Key Points:

LPATH clusters diverse molecular pathways into distinct classes or routes.
The tool leverages text-string similarity for pathway matching.
Successfully applied to alanine dipeptide's C7eq to C7ax conformational transition.

Conclusions:

LPATH offers a novel approach to analyzing complex molecular pathways.
The tool provides physically reasonable pathway classifications and probabilities.
Applicable to both weighted ensemble and conventional simulations.
