Fine tune CHGNet with GGA+U calculations using non-standard U

[enricosireci]

Hi everyone. I am trying to fine-tune the CHGNet pretrained potential with my own GGA+U calculations where I apply the Hubbard correction on Mn. To do that, I am trying to correct the energies to make them compatible with the pretrained potential through MaterialsProject2020Compatibility. However, this seems to work only for Mn U = 3.9 eV, while my calculations were carried out using U = 2.5 eV. Can anyone clarify how I can solve this issue? Thanks!
