RHF rotating orbital

Dear Molcas users,

Is there a way to rotate orbitals in an SCf jobs?
I want to have the right orbitals before using them in different RASSCF jobs.

If not I guess I can Alter orbitals in each individual RASSCF jobs.

Best,

Re: RHF rotating orbital

What do you mean with "rotate"?
If it's rotation in real space, try mort (in Tools/mort)
If it's just changing the order of the orbitals, you can use Pegamoid to select the active space and save the file with the "pre-selected" orbitals
If it's a unitary transformation of the orbital coefficients... you'll have to do it yourself.

Re: RHF rotating orbital

Sorry for not having been clear (each software uses different word for the same action). I would like to change the order of orbital in &SCF like the keyword Alter does in &RASSCF.

Re: RHF rotating orbital

As I said, you can use Pegamoid. Or you can manually edit the ScfOrb file (it's a text file) to change the order of coefficients, energies, and occupations, or just modify the "#INDEX" table at the end: "i" means inactive, "s" means secondary (virtual), "1", "2", "3" mean RAS1, RAS2, RAS3.
