Prodrg does very good job in guessing atom types and bond orders. Once it guessed things right it does extremely good job in generating bond lengths, angles etc. But it still depends on accuracy of coordinates. You need to check carefully bonding orders before using them in refinement. You c

Hi Paul, the command phenix.ready_set model_with_unknown_ligand.pdb will create a CIF file for all novel ligands in your input PDB files. You can do it from the command line or using the main GUI. phenix.elbow will do this too. Pavel. On 6/21/10 3:40 AM, Paul Lindblom wrote: Hi all, I n

Hi Paul, you can use PRODRG server at Dundee university ( http://davapc1.bioch.dundee.ac.uk/prodrg/ ) It generates libraries in different formats... you just need to copy/paste in your preferred text editor. HTH Marco Paul Lindblom wrote: Hi all, I need to create a cif file for a new liga

Hi Paul, Usually I just Sketch the molecule, I make sure that the bond types are OK (single, double, aromatic etc.) and I do an idealization in Sketcher, then use the resulting .cif file in RefMac. Flip Paul Lindblom wrote: Hi all, I need to create a cif file for a new ligand that does not

Hi all, I need to create a cif file for a new ligand that does not exist in the pdb, so far. Normally refmac created such a cif file when I merged the ligand to the structure, but this time it stops with a "fatal error". I think the alternatives are "sketcher" and the prodrg server. Can anybody te
