Do you need also "core" electrons or just "all-electron valence" electrons? In PAW it is rather straightforward to write the all-electron (i.e. not pseudized) charge density, but if you need core electrons as well, they have to be read from atomic data, or invented. The straightforward way to compute the electrostatic potential from the charges involves FFTs and it is not very suitable for core electrons. I would like to know how to make it requires some programming work, see above, and maybe some good ideas > , or alternative programs that can extract ESP easily from PW scf > calculations. > "easily", I do not think it can be Paolo -- Paolo Giannozzi, Dip.
