Dear Pausali, It seems that you are study the layer structured TMD crystal, not the monolayer. How about changing cell_dofree from '2Dxy' to 'all' or 'ibrave'? Cheers, Yun Dr Yun Wang | Senior Lecturer PhD Deputy Head of Discipline, Chemical Science Centre for Catalysis and Clean Energy |

Hello Paolo, its version 6.4. The newer versions I have not compiled yet, but once I do that I will let you know asap. Towards the first question I asked: 1. Usually I start out with NEB with "no-CI". Then after this calculation converges, I restart my calculation with the same input script and

Hi: Yes, this is related with the fact that you are probably creating your input file for pw.x inside a shell script (using "EOF") where you also call to the program. In my case it would stop like waiting for input without doing anything. To solve it, you only have to create your input file

Something similar was reported some time ago. I don't remember exactly what and when and what was the problem and what was the solution, but I am quite sure it wasn't a problem of QE. Please verify that your data file contains the correct syntax and the correct number of k-points. Also please
