you should ask this to whoever generated that pseudopotential. The FHI format does not contain all the info needed to be used with other codes. You should in any case know how many valence electrons there are. Occupancies are used only for starting the calculation and are not critical. The correct angular momentum is important. I think it is s,p,d,f, in this order, but no warranty. > If my converted pp is not precise, how can I solve this? Which > parameters should I change to enhance the precision?? this is a big question that doesn't have a quick answer.
