Dear Paolo, >you can supply atomic positions in crystal coordinates.
That is I actually did. >No warranty >that the crystal axis we use are the same of vasp, though, but in >the case of simple orthorhombic, the choice of the axis is obvious Yes, you are right. The settings of rhombohedral unit cell in VASP are different in PWscf, so I must use ibrav 0 and CELL_PARAMETERS. Thanks, Sergey
