Jin, Make sure you refine a,b,c in the last refinement cycle. If you fix the at some points the error "bars" are gone. Peter Zavalij X-ray Crystallographic Center University of Maryland College Park, MD 20742 Phone: 301-405-1861 From: Peng, Jin [mailto:jpe...@tulane.edu] Sent

Dear Jin Peng, The uncertainties for the lattice parameters (and all the other fitted parameters) are in the LST file (list file). They are shown as separate numbers for the lattice parameters and the uncertainties, like so: 13.88843 13.88843 6.53524 0.000350.00035
