User Reviews

  • Initially installed on windows 64 is not working because of missing a dll file. This file can be installed from microsoft site: www.microsoft.com/en-us/download/details.aspx?id=8328 Then all is great!

  • Avogadro is good but it does certainly have its limitations. As pointed out there are no Python bindings available for Windows, except when using the very out of date version 1.0.1, which can prevent one from using some of the more advanced features. As far as support well the mailing list (avogadro-discuss@lists.sourceforge.net) I found quite helpful. Something worthwhile noting for all those intending to use this software to create molecular images -- the element colouring palette is etched in stone.

  • Hello, somebody known how to calculate Avogadro software the cross section, maxime diameter, and Surface total area of the molecule? Please I need this information. manuelmorrone@gmail.com

  • Most of packages for Windows are without Python console. I need the feature and find avogadro-1.0.1-python-win32.exe, which is the only package with Python console. I hope the developers will enable the console in the future.
