Avogadro2

11 November 2020

Advanced molecule editor and visualizer (beta).

Overview

Avogadro2 is a user-friendly molecule builder and editor. It offers flexible rendering and a powerful plugin architecture for developers. The program supports interactive building of molecules with integrated molecular mechanics and a fragment database. Input generation for GAMESS, MOPAC, or Gaussian calculations is provided. For visualization, the program supports crystallographic unit cells, isosurfaces and orbitals from Gaussian cubes and OpenDX.

What's new in Avogadro2

Version 1.2.0:
  • Support for the ORCA quantum chemistry package, including input generation and output parsing
  • Improved support for MO calculations, including orbitals with F, G, H, and I angular momentum
  • Support for exporting VRML models of atoms, bonds, surfaces, and orbitals (e.g. for 3D printing)
  • Support for perceiving molecular symmetry on Mac and Linux using the libmsym library (i.e., Properties -> Symmetry)
  • Updated links to the new Avogadro website, manual, and discussion forum
  • Fixed support for compiling with the Eigen3 library up to version 3.2.8
  • Improved support for space groups through spglib
  • Updated translations, now including over 25 languages in addition to English
  • Fixed a bug downloading from the Protein Data Bank
  • Fixed a bug fetching molecules from the network, including the "chemical by name"
  • Fixed a bug when naming molecules from the NIH chemical resolver website

I remember using ChemDraw and the 3-D version almost 10 years ago to model nanotubes and nanopeapods (right after peapods were discovered, in fact). This free program does what they did and much more. It's a lot of fun to build little molecules and see how they form, especially when you turn on the auto-optimization that calculates how the molecule would actually position the component atoms. It really does let anyone play around with building and interacting with molecular structures. There are some weird interface issues. First, the keyboard commands to switch between tools are function keys, and don't seem to work on Macs, even if you toggle the function-key setting in System Prefs. Second, closing the last window quits the program. The fragment library doesn't appear to work right now, so it isn't possible to import the sample molecules that come with avogadro. Nevertheless, if you're interested in molecular engineering, nanotech, or anything in that category, this is a free way to have access to a tool that lets you play around. It looks like it has much more advanced features as well, but I can't speak on those with any authority.

This is a public beta of Avogadro v2. At the moment, there is not the usual level of interface polish, (particularly on the Mac) and many features are lacking compared to Avogadro v1.1.x. On the other hand, rendering performance on large molecules is vastly improved with optimized OpenGL code. This will be the future of Avogadro.
