At one time I thought this was working but it is not. Under both Avogadro2.appimage and windows avogadro2 I have been working with the latest version of MOPAC (2023). A2 writes the .mop file. I run it through MOPAC and obtain an .out file, but that file gives an error when I try to load it. Same error for both appimage and windows..on several different structures.
I would not be surprised if the MOPAC files have changed over the years.
Whenever you have a problem with “this file doesn’t read properly” it helps to have the file itself. Can you please post it? Thanks
