Re: [ccp4bb] Rigaku CrystalTrak Web not working
Hi Johannes, just making sure that there is no misunderstanding. I am currently working in Dr. Frank Sicheri lab at Mount Sinai Hospital in Toronto, ON, Canada. Is this the local installation you are talking about? I am just using my Czech email account, since I have the CCP4BB already set up on this account...

Re: [ccp4bb] Any guesses? - What is this feature modelled (wrongly) as 3 waters
Hello Can you provide the list of all the components in the crystallization experiment? Except the protein of course. What is the resolution of the structure? Have the B-factors been refined anisotropically? At what sigma level is the 2Fo-Fc map and Fo-Fc map (doesn't seem to be shown)? If I were to take a wild guess - the size might accommodate ethanol (glycerol and ethylene glycol would be too big already and the geometry doesn't look right for metal ion complex either).

Re: [ccp4bb] why does Coot ignore CONECT?
Hello Eleanor, We tried to follow your suggestion. The atoms to be linked were 1.46A apart in the input pdb model and we ran 10 cycles of refinement in Refmac with the "make link between" option chosen in either "defined in the file or residues are close". After the refinement we saw the linkage as dotted line and the distance between the atoms was 2.2A (in other words they moved apart instead of forming a covalent bond).

[ccp4bb] why does Coot ignore CONECT?
Hello, I have a question, can anyone explain, why does Coot not display a covalent bond manually specified by CONECT line in a pdb file? The same file shows the covalent bond if displayed in Pymol.

[ccp4bb] D amino acids in Coot
Hi everyone, if I load D-Ala (Get monomer DAL) in Coot and superpose (LSQ) it with regular L-Ala (ALA), the two amino acids look identical to me (not mirror images of each other), see attached image. I have the same problem with D- His. Is this normal, or am I missing something?
