Dear List, I am trying to use Psi4 in combination with the free webmo server and was able to get it to work. However, in trying to go through the Introductory Lab (Atomic Radius) I noticed that the Molecular Orbital option is missing from the PSI4 job options menu. I have the latest versions of both PSI4 and WebMO on a linux machine. What is it that I am missing? Thanks for any pointers. Best regards, Alex.
