pymatgen/io/vasp/inputs.py:1856: UnknownPotcarWarning: POTCAR with symbol Pr has metadata that does not match any VASP POTCAR known to pymatgen. The data in this POTCAR is known to match the following functionals: ['PBE_52', 'PBE_54', 'unvie_PBE_52']
When post-processing results from a TbO2 relaxation, I get the same UnknownPotcarWarning and pymatgen interprets the Tb ions as Ce when printing output structure data, plotting DOS, etc.
How should this behaviour be handled since the post-processing of VASP results is being affected in the case of TbO2.
Can results generated by pymatgen modules on raw VASP output data be interpreted as the same when this warning is not present? Does this affect the integrity of the results in a general sense?
