Hello, First, thanks for your answers. I tried in another machine (with the same version 4.2.1) and the result are different, but are still out of range, first I obtained: [-0.2092:1.2504] and now [-0.1951:0.981], I ran the same scf and elf input file, but in different machines. The range is the "thermometer" that shows xcrysden?, right? maybe I am missing something... :(
Thanks a lot!
