[phenixbb] joint xn refinement question

[Walter Novak]

Hi,

I am new to the list, but I didn't see this issue in the list archive.  
I am doing a joint refinement using x-ray and neutron data (each set  
is ~2.0 Å). I added H positions using reduce and have been switching  
to Ds as the density suggests for exchangeable positions. My problem  
is that I cannot seem to get the H (or D) positions to refine into the  
neutron density. Perhaps I need an additional command, so I am  
attaching my refinement script. I can provide a few pictures from coot  
to demonstrate if helpful.

Thanks!
Wally
