[QE-users] Electron-Phonon calculation with Hubbard-U in QE

Dear Users,

I am attempting to calculate electron-phonon coupling (EPC) within the
GGA+U framework using Quantum ESPRESSO (v7.4.1). However, I encounter the
following error:

*Error in routine phq_readin (1): Electron-phonon with Hubbard U is not
supported*

Could anyone please advise whether EPC calculations with Hubbard-U are
currently supported in QE, or if a specific version or modification (e.g.,
to pseudopotentials or code) is required?

Warm regards,

Koyendrila
