Thanks, now i have both potentials taken of the same reference. But i modify the input file, just to read only one compound the palladium(this for answer your question"do they work for the individual pure systems?"), but in this case the failure is different, he show me (Invalid mass value (…/atom.cpp:1041)) i don’t can understand what happened, thanks.
here i show you the data file for a individual pure system
