Basic Usage

PythonCLI

from ase.io import read
from aseview import MolecularViewer

trajectory = read("md_trajectory.xyz", index=":")
viewer = MolecularViewer(trajectory)
viewer.show()

aseview md_trajectory.xyz

---

Frame Selection

Index	Result
-i :	All frames
-i 0:10	Frames 0-9
-i ::2	Every 2nd frame
-i -1	Last frame only
-i -20:	Last 20 frames

---

Energy Plot

Display energy synchronized with animation:

viewer = MolecularViewer(trajectory, showEnergyPlot=True)
viewer.show()

Energy is extracted from atoms.get_potential_energy() or atoms.info['energy'].

---

Force Vectors

Display force vectors on atoms:

viewer = MolecularViewer(trajectory, showForces=True, forceScale=2.0)
viewer.show()

---

Animation Controls

Control	Description
Play/Pause	Toggle animation
Frame slider	Jump to frame
Copy frame	Copy current frame as XYZ
Copy all	Copy entire trajectory

---

Saving

viewer = MolecularViewer(trajectory, showEnergyPlot=True)
viewer.save_html("trajectory.html")
