# How to generate a input file for gaussian in Avogadro 2? [duplicate]

I made auto optimization working by installing openbabel using sudo apt install openbabel.

Is there any way to make Gaussian extension working by doing something?

I've the avogenerators scripts in /home/jupiter/.local/share/OpenChemistry/Avogadro/inputGenerators/OpenChemistry-avogenerators-eddfee4.

• Is your problem the same one described in this past question? How to make the input generator plugin work in Avogadro 2 on GNU/Linux?. The solution is to compile Avogadro 2 from source. Oct 6 at 14:15
• What version of Avogadro2 do you have installed? How did you install it? The latest version (1.95.1) fixes a number of packaging bugs related to input generators. Oct 9 at 14:37

You can use OpenBabel directly to obtain the Gaussian input from command line.

OpenBabel supports two types of Gaussian input generation:

• Gaussian 98/03 Cartesian Input
• Gaussian Z-matrix Input

To run OpenBabel:

obabel [-i<input-type>] <infilename> [-o<output-type>] -O<outfilename> [Options]


Take a look at this answer for information about all the formats OpenBabel work with.
