Custom guess for Hartree-Fock

Dear Psi4 Community,

is there a way to use initial guesses that I have calculated myself instead of the sad guess?

The coefficient matrices, that I want to use for this purpose, are currently in the form of numpy arrays.

Kind regards

While there is a way to do this, it operates by saving a wavefunction object to disk. If you can express this initial guess you’ve calculated yourself as a Psi4 wavefunction object, it can be done.

Do your initial guesses obey point group symmetry? Do you want to use your guesses for systems with symmetry? Are your guesses associated with a specific basis set?
