Avogadro is an advanced molecule editor and visualizer designed for cross-platform use in computational chemistry, molecular modeling, bioinformatics, materials science, and related areas.
Avogadro can read from and write to a large number of input and output formats for a large number of computational chemistry packages as well as perform visualisations and animations of MD/AIMD and trajectories. For a full list of capabilities and supported computational chemistry packages, see the Avogadro home page
Access to the avogadro binary is given via the module system, e.g. do a module load avogadro/1.1.0 and then run with the avogadro command. Remember that you will need to be logged in with X forwarding or the current VNC solution available to make use of the interface.
