ArgusLab is a free, Windows-based molecular modeling, graphics, and drug design program popular among students and researchers for performing basic computational chemistry and molecular docking simulations. Developed originally by Mark Thompson, it features tools for drawing chemical structures, optimizing geometries, and calculating molecular properties.
Mastering molecular modeling in ArgusLab requires understanding its interface and sequential steps, which range from basic model building to complex ligand-protein docking. 1. Structure Building & Editing
Before running any advanced calculation, you must correctly sketch your target molecule on the workspace canvas using the integrated Builder Tool. Open a workspace by clicking File →right arrow New. Activate the Builder Tool from the toolbar menu.
Select atoms, functional rings, or predefined amino acids from the builder tabs.
Add components to the workspace using a left-click or right-click depending on your version. Link atoms together by clicking the Automatic Bond icon.
Saturate open valences instantly using the Add Hydrogen tool.
Modify specific elements by right-clicking an existing atom and selecting Change Atom. 2. Geometry Optimization
Raw hand-drawn molecules have unrealistic bond lengths and strained angles. Geometry optimization refines the coordinates to find the lowest potential energy state. Molecular Docking Simulations with ArgusLab
