> The QE version is 7.3.1. The pseudopotential was copied from the SSSP library, and as you can see, I used the parameters that were suggested there. I've tried several suggestions from the user list, but none of them have worked. In fact, I changed the "cell_dofree" variable to both "all" and "xyz", and both had the same errors. My input is below.<br>
