Curie Web Demo

-

Dock and Report performs molecular docking using AutoDock Vina, generates visualisations using PyMOL and then finds protein-ligand interactions using PLIP. It then compiles all of this into a PDF report and emails it to you.

+

Curie-Web is a part of The Curie Project which aims to make the process of Computer-Aided Drug Design as fast as possible.

+

The following are the currently active modules
