Dynamics (RMSD/RMSF)

Source: src/lib/md/MdDynamicsPanel.svelte, src/lib/md/MdAnalysisPane.svelte

Overview

Computes RMSD (Root Mean Square Deviation) and RMSF (Root Mean Square Fluctuation) from MD trajectories to quantify structural stability and per-atom flexibility.

Components

MdDynamicsPanel

Interactive panel for RMSD/RMSF computation and visualization.

MdAnalysisPane

Parent pane orchestrating all MD analysis tools.

Metrics

RMSD

Measures how much the structure has changed from a reference frame over time.

RMSF

Measures the average fluctuation of each atom around its mean position.

Server API

Endpoint: POST /api/md/rmsd

Parameters

  • reference_frame — Index of the reference frame (default: 0)
  • atom_selection — Which atoms to include
  • alignment — Whether to align frames before computing
