Dear all,
I have three questions as follows,
1.If there are three or more atoms in the same site(e.g.,LiNi1-x-y-zCoxMgyTizO2��,how 
to set the constraints and refine their fractions?
2.When setting atoms' valences and fractions,whether is the principle of charge 
neutrality considered?
3.How can I copy the plots of dmplot or GSAS to the files of Word2000?
