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.
