Some remarks about your input file: 1) the error message means that the number of bands you specify is not enough to accommodate all the electrons, usually you do not need to specify nbnd in scf/relax calculations (whereas it is needed in bands/dos calculations if you want to span a given rage of unoccupied states). In my experience, it is much better to leave out all the variables you do not need explicitly.
2) I would use the most recent version of QE 3) wf_collect I think is no longer used 4) you are using PAW pseudopotentials but you are using the default value of ecutrho = 4 * ecutwfc. While this might be enough in some cases, in many others values as large als 8*ecutwfc (or even more) might be needed. Did you check it? 5) as it is, it is correct, but if you need an orthorombic unit cell you may use the corresponding value of ibrav (with the corresponding parameters) in place of the CELL_PARAMETERS card. The case in which you want to optimize the unit cell is of course different 6) extension in pseudopotential file names refer to the versions of the code used to generate them. Something more about the naming convention might be found here: https://pseudopotentials.quantum-espresso.org/home/naming-convention 7) you do not need to specify symmetries in the input file. In your case you are getting rid of them, instead ( nosym = .TRUE., noinv = .TRUE.). Check if this is exactly what you want, because using symmetries (if any) might (even significantly) reduce the workload of your calculation 8) in order to better control and quantify the convergence of your calculations, you might want to sample each direction in reciprocal space with a similar way (that means that the distance between two neighbor k-points located along the three reciprocal vector directions is as much similar as possible). For this reason, a better choice than an n x n x n grid is an n x m x l grid, where the three integers are in the inverse ratios of the corresponding lattice parameters in real space. Example: a = 8.4, n = 8 => b = 11.1, m = 8 * 8.4/11 ~ 6 Giovanni -- Giovanni Cantele, PhD CNR-SPIN c/o Dipartimento di Fisica Universita' di Napoli "Federico II" Complesso Universitario M. S.
