Ensure you also have a corresponding coordinate file ( .pdb or .dcd ).
The psf.rar archive contains a molecular topology file (PSF) essential for defining the structural connectivity of a biological system. It provides the "blueprint" for simulations, specifying how atoms are bonded, their types, and their charge distributions, which cannot be determined from a coordinate file (like PDB) alone. File Format: Roshal Archive (RAR). Internal File Type: Protein Structure File (PSF). Primary Compatibility:
Standard for large-scale biomolecular simulations. X-PLOR: Often used for structural refinement. VMD: Used for visualization and structure building. 3. Detailed Contents
Explicit values for each atom's mass and partial charge, used by the force field to calculate physical interactions. Connectivity Tables: Bonds: Explicit pairs of atoms that are chemically bonded. Angles: Triplets of atoms forming specific bond angles.
A standard PSF within this archive typically includes the following sections:
Quartets of atoms defining rotation around bonds.
