<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;

bit smaller and larger than 90. But the symmetry still does not work and the
error information is still that”-3 missing”.</span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Actually, a problem appears from the very beginning when I
accepted the structure file the program suggested. An error information “Error
– incorrect space group symbol” appeared at that time. The space
group calculated by sgroup is 12c2/m. Then I do “nn” and “sgroup”,
it is still fine. But for “symmetry”, I was told “-3 missing”.
