List information regarding ID, classification, experimental technique, chains, solvents, inorganics, ligands, and ligand binding pockets in macromolecules present including proteins and nucleic acids.
The supported input file format are: PDB (.pdb), mmCIF (.cif)
All available information.
Min and max coordinates for bounding box along with its size.
Number of chains and their IDs. This is also default behavior. --countResidues Number of residues across chains. The chain residues are identified using polymer selection operator available in PyMOL. In addition, the non-standard amino acid residues are listed.
Print this help message. --header Header information including experimental technique information along with any available resolution. This is also default behavior.
A comma delimited list of input files. The wildcards are also allowed in file names.
Inorganic residues across chains. The inorganic residues are identified using inorganic selection operator available in PyMOL.
Interface residues between specified pairs of chains.
Pairwise comma delimited list of chain IDs for the identification of interface residues. Each chain ID may contain mutiple chain IDs delimited by a plus sign. For example: A+B,C+D chain pair specifies interface between chain complexes A+B and C+D.
The interface residues are identified between first two chains in input files by default.
Methodology for the identification of interface residues between a pair of chains in an input file. The interface residues may be identified by change in solvent accessible surface area (SASA) for a residue between a chain and chains complex, distance between heavy atoms in two chains, or distance between CAlpha atoms. Possible values: BySASAChange, ByHeavyAtomsDistance, or ByCAlphaAtomsDistance.
Cutoff value used by different methodologies during identification of interface residues between a pair of chains. The default values are shown below:
Ligands across chains. This is also default behavior. The ligands residues are identified using organic selection operator available in PyMOL.
Chain residues in ligand pockets.
Distance in Angstroms for identifying pocket residues around ligands.
Solvent residues in ligand pockets. The solvent residues are identified using solvent selection operator available in PyMOL.
Inorganic residues in ligand pockets. The inorganic residues are identified using Inorganic selection operator available in PyMOL.
Phi and psi torsion angles across chains in macromolecules containing amino acids.
List all phi and psi torsion angles for residues as a single group or split them into the following categories corresponding to four types of Ramachandran plots:
Precision for listing phi and psi torsion angles.
Solvent residues across chains. The solvent residues are identified using solvent selection operator available in PyMOL.
Surface and buried residues in chains.
Solvenet Accessible Surface Area (SASA) cutoff value in Angstroms**2 for surface and buried resiudes in chains. The residues with SASA less than the cutoff value correspond to burried residues.
List residue IDs for surface and buried residues during listing of the distribution of these residues for '--surfaceResidues' option.
Location of working directory which defaults to the current directory.
