Dear Koyendrila, The electron-phonon calculation with Hubbard U corrections is implemented but not extensively tested, that's why it is disabled. You can enable it, test it, and use it if the tests are ok.

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
