Dear Espresso fans,
I would like to make a series of calculations in different lattice parameter values. If I understand correctly, the atomic positions should be in units of the lattice parameter "a" (default) in order for them to stay the same for every lattice parameter. So, I assume each Cartesian coordinate in Ang should be a fraction of lattice parameter: X/a But, does the lattice parameter should be in bohr (like in celldm(1)) or in Ang as well ?
