Guys! I guess the line gpaw Fe -x bcc --cubic -a 2.84 -M 2.3 --xc=PBE --kpts=8,8,8 --h=0.18 --fit in https://wiki.fysik.dtu.dk/gpaw/tutorials/lattice_constants/lattice_constants.html does not work with the latest GPAW release? It would be nice to have an updated version of the Tutorial section on the GPAW website. Thanks and best regards Dani
