Dear Hongyi Zhao, I understand that and have also checked the Seek-path online tool at materials cloud website. However I could not figure out a way to get many q (or k) points along the paths. The matdyn.x needs many points along the path as an input, let's say 400. That's why I have made

Dear QE users, I could not find a script or online tool for automatic generation of explicit q points along BZ paths, necessary as an input for matdyn.x (PHonon). So, I decided to write a script based on the Seek-path python module (https://pypi.org/project/seekpath/). Perhaps someone can find it

Yes, we are testing and comparing planewave calculations with dftb in the same conditions (TS and MBD). Usually I'm using the non-local vdE-df2, which, in my experience, is working well. But for this particular project we need TS (and MBD). Thanks to Paolo and to you for the reply. Carlo Il

Dear Carlo, Is there any particular reason why you want to use the TS scheme? If not there are several benchmarking studies (e.g. https://doi.org/10.1063/1.4981528 ; https://doi.org/10.1063/1.5030493 ; https://doi.org/10.1016/j.icarus.2021.114611) demonstrating that the TS and the D2 scheme
