Hi Pavel, but couldn't you simplify it further by omitting the word "atomic" throughout? In fact isn't "group (an)isotropic Atomic Displacement Parameter" a contradiction in terms? Surely it can be either a group parameter or an atomic parameter but not both at the same time? I think the worms are already out and making good their escape :). Cheers -- Ian
