As in Avogadro 1.2.0 in windows or Linux, I would like to make use of constraint based geometry optimisation (i.e., doing geometry optimisation for selected atoms) in Linux with Avogadro 1.97.0, where I can’t even select atoms in it. Please let me know how to perform this and please help me out with the issue of selecting atoms.
Thanking you,
Snehith.
