Try Chekcell and Truecell (they work as one program) to test your
solutions. You can import a list of solutions from a CRYSFIRE file.
The latter is generated by both Treor and/or Dicvol, if you run them
from Fullprof Suite. Or you can run any indexing program from
CRYSFIRE.

AvdL> Dear all,
AvdL> It is generally assumed that a high value of the M20 index gives a 
AvdL> high probability that the solution is correct. I have a particular 
AvdL> problem for which I have a couple of different solutions with M20 
AvdL> between 40 and 100. The problem resides in the fact that the a and c 
AvdL> axes of the monoclinic cell are much larger (both around 20 A) than 
AvdL> the b-axis (3-6A?) The solution depends therefore on the angular 
AvdL> range which is taken for the indexation process. Taking the first 20 
AvdL> reflections with significant intensity gives a 6A b-axis with the 010 
AvdL> reflection as the last one in the list. Taking 5 reflections more, 
AvdL> the length of the b-axis decreases and the 010 remains the last in 
AvdL> the list. And so on. The compound is organic and there is not much 
AvdL> scattering left beyond 2Theta=30degr, giving a total of 31 
AvdL> reflections to be used for the indexation.
AvdL> How to pick up the right solution between these high M20 solutions? 

AvdL> Thanks in advance, Arie
