thank you for you response. I tried to do something like that, but I cannot understand the content of the file "al.rho.dat". I suppose that the density is in the big block of 6 numerical columns "DATAGRID_3D_UNKNOWN", but, How is ordered that block? , In what order should I read it?. I need the electronic density rho(x,y,z) for a further calculation. thank you again. jorge
