Hi,
I have partial solution from MR on a crystal with dimensions
52.729   60.364  142.908  90.00  90.00  90.00 P 21 21 21.
I have SAD data from another crystal with dimension
53.860   61.470  142.492  90.00  90.00  90.00 P 21 21 21.
My question is can I treat both as isomorphous and combine data from both of them and use my MR as model with Autosol.
What is the maximum difference in unit cell dimensions allowed to consider two unit cell isomorphous?
If you can point to some references/examples that will be highly appreciated.
Thanks a lot.
