Dear Francois,If you know the exact fraction of each bond valence at the same 
site, you can solve this problem. For example, the element A has two different 
states V1 and V2 in x site. V1 occupies 60%, and V2 occupies 40%. Then you can 
edit your file, copy the oiginal row where the atom lie into another row. The 
original row (for V1) and the new row (for V2) are the same except occupancy, 
and the occupancy needs to be updated, namely, the original occ multiplies 
their respective fraction of different state. Here, original occ*0.6 for V1, 
and original occ*0.4 for V2.
Best regards, Daxu

   Dear Rietveld users, I am currently using Bond_str from the fullprof suite 
to calculate the valence of my different atoms. I would like to calculate the 
bond valence in the case of mixed sites with different oxidation state. Does 
anyone have found a solution to do this calculation of the mixed site in the 
CLF file. Or is there another nice program to calculate Bond Valence , 
distortion, global instability, …
  Best regards!
