Multiwfn doesn't support restricted open-shell for CDA, you have to use unrestricted formalism

Hello,
Sorry for this late question ... What's better, unrestricted or restricted open shell DFT?

Charge decomposition analysis of open-shell system

Dear Mutiwfn users.

I am dealing with Charge decomposition analysis using ORCA and multiwfn.
My molecule is an open-shell system (contain an odd number of electrons). I divided it into two fragments: the first enclosing an odd number of electrons and the second containing an even number one.
Are there special settings, at the level of the orca and mutifwn, to perform this operation?

Thank you very much..
