I have seen some crystallography simulation softwares at other schools.If you have one please reply ASAP.Please post the solution.Crysallography is important so please think over the solution. Thanks, Satyanarayana. __________________________________________________ Do you Yahoo!? U2 on LAUNCH - Exclusive greatest hits videos http://launch.yahoo.com/u2
