<div dir="ltr">On the topic of twin refinement, I think it would be useful to implement the input of multiple twin laws. Xtriage identified three twin laws, but I had to refine in Refmac5 because only one could be entered in Phenix.<br>

In terms of actual implementation I have this in mind:<br>

Of course that would not stop (me) from implementing better ideas
should they arrive. However the paper mentioned above pictures a
clear image of the problem that we are going to address.<span class="HOEnZb"><font color="#888888"><br>
