[phenixbb] refinement error with ligand

[Christian Roth]

Dear all,

I started a refinement of one of my structures using the GUI of phenix (Version 
1.6). I used the options of adding hydrogens and dis a suimulated annealing. I 
used the output file and corrected it manually using Coot. I incorporated a few 
Ethylenglycol Monomers which might have bound.  I merged everything wrote the 
file out  and loaded this pdb in the GUI. I got an error which might be du to 
the fact that I didnt specify a CIF file for the ligand. I started ready set 
from the GUI to check the pdb and used REEL to create a CIF File. I added the 
CIF-File to the  File list and tried to start again phenix.refine using the 
hydrogen option but no sim. annealing. However I got always the following 
error log:

    ... (remaining 6 not shown)

I looked in the pdb for this atoms, but I cannot find them.
When I use a cif file created directly by phenix elbow using command line and 
when I did not use the update hydrogen button the refinement works. But the new 
residues as well as the EDO molecules have no hydrogens in riding positions. 
Do I have to remove all hydrogens and attach them again for every cycle?
One Refinement runs for more then 5 hours regardless I use sim annealing or 
not. This seems to be very long for me. Maybe I want  too many optimization 
steps?

Could anyone explain me what goes wrong here. I am no so much experienced with 
phenix and now I run out of ideas. 

Thanks in advance
