Problem refining structure, error message
Hello, I’m building a structure at the moment, and I have since removed lithium ions from structure. However, when I go to refine using phenix, I get the error message: “No atom selected: name LI and Chain F and rename LI resseq 8” I’ve tried using earlier files, prior to my addition of lithium ions and I still get the same error message. I’m using Phenix version 1.10.1-2155-000 Could anyone help me overcome this error message? Cheers, Nat _____________________________ Natalia E.

Hi Nat, Open your PDB file in text, remove information of Li in 'remark', save the pdb file and use it for refinement. This should work.

Hi Natalia, Are you using old settings to refine your new structure? If you're using the GUI, try starting with a new job (e.g. clicking on phenix.refine instead of restoring an old job). If you're using the CLI, you can send me your parameter file (ends with .eff) and I can take a look. There could be a selection for Li that is floating around if you're using the same parameter file from and earlier job. Let me know if that doesn't work for you. Thanks! -- Billy K.

phenix.refine does not use REMARKS. you must have somewhere the selection line.
You probably use the automatically generated metal restrains and the atom name there does not match the one in PDB.
Can you share your phenix.refine command line?

phenix.refine does not use REMARKS.
Actually it uses some information from REMARK records (if it finds it and validates it is good, otherwise continues), such as TLS selections, twin operator, perhaps something else which I forgot. Recently it started outputting LINK records for internally generated extra restraints, such as metal coordination or ligand linking. I can't remember if we read them back and if we do what happens if LINK defines nonexistent (obsolete) atoms. Pavel
Thank you everyone for all your helpful suggestion! Easily my favorite message board!
What solved the error was Georg’s suggestion, being to got to the ‘Utilities’ menu and selecting ‘clear custom selections’.
Happy weekend!
Nat

Just to answer Pavel, the only reading of LINK records is done by an
obsolete script for converting them to .edits.
