Hi all, Thank you Matt for bringing up this issue. Massimo Nespolo has been fighting for the correct description of structures, specially focusing on symmetry and proper terminology, for years (see his many articles on the misuse of lattice, sublattice, superlattice, etc). He has, as well, been

Re: Crysfire

Hi Rhine, Crysfire requires your peak positions to be ordered from lower to higher Q or 2theta (being Q=1/(d^2) in crysfire, instead of q=4*pi*sin(theta)/lambda) but they both grow in the same direction), which means higher to lower d-spacing. I don't think there is a command to order your peak

that always resembles tetragonal symmetry. In my experience even in highly pseudo-symmetric cases the cell parameters finally converge to slightly different but stable values, which is hard to achieve in the case of using the wrong symmetry. Hope this helps, Best regards Leo Dr. Leopoldo
