RMSD in Molecular Dynamics: What Does It Actually Tell You?

By BioDockify Computational Research Team · August 9, 2026 · MD Analysis

A deep dive into RMSD analysis in molecular dynamics simulations. Covers what RMSD measures, how to interpret values, common pitfalls, and why RMSD alone is insufficient for stability assessment.

Scope & Limitations

RMSD depends on reference structure choice Does not capture local flexibility (use RMSF) Can be misleading for multi-domain proteins
