[Pw_forum] about lattice basis vectors?

[Fan Yang]

Dear everyone,
         I have a simple question about the setting of PWGUI, namely, does the lattice basis vectors in "CELL_PARAMETERS" refer to real lattice or reciprocal lattice?  and what does the lattice type mean, since it has only two choices-cubic and hexagpnal?
         Thanks in advance.
