phenix.model_idealization

Description

The program for geometry idealization of protein secondary structure.

Program reads model from .pdb file, extracts information from HELIX/SHEET records if available and replaces these helices and sheets with geometrically ideal ones while preserving initial atom positions as much as possible.

If HELIX/SHEET records are not available, it will try to find them automatically. Correct secondary structure annotation is extremely important for proper functioning of this program. Incorrect annotations most likely will lead to distorted model. Please refer to SS documentation for more details.

If input .pdb file contains unknown ligands, their description should be supplied. This description can be obtained using eLBOW (GUI version)

The model should not contain non-standard protein residues inside secondary structure elements. The presence of unknown (UNK) residues in model (outside SS elements) is not advised because appropriate geometry restraints will not be generated for them and therefore such residues may be significantly distorted.
