[phenixbb] a question on LSTc refinement

[fn1 at rice.edu]

Hi all,

I read some previous post on LSTc [SIA(alpha2-6)GAL(beta1-4)NAG]  
refinement, but i still cannot figure out how to refine it in PHENIX.  
In the current version of phenix, i still could not find the ALPHA2-6  
link. Does anybody have such experience?

Another question is that, sialic acid (SIA) is in the monomer library  
of phenix. But when i run on the pdb directly, it will give the error  
information like, "unknown bond type for O1A and O1B".  Though this  
error could be solved by provided the cif file generated by  
phenix.elbow.

Thank you very much!
