Dear PWSCF users, I'm trying to find out how to interpolate a radial atomic wavefunction (obtained from the pseudopotential generator) onto the linear grid to integrate against the sc potential in a perturbation theory framewrok. I've looked through the code and searched the archive to find out if this function already exists but couldn't find anything. It would be of great help if I could get help on this. Does this (or anything similar) already exist or should I write one of my own? Also do you see any problems with this procedure in and of its own such as loss of accuracy.
Many thanks in advance and best regards, Hande
