[Pw_forum] Magnetism
Dear QE users, I want to do a PDOS calculation on a TiO2 doped with Cr which is magnetic. Attached is my input file. I have succeeded in doing the scf, nscf, dos but when i do the PDOS, the calculation fails with an error from davcio : error # 10 error while reading from file. Please tell me what the problem is.
