Automatically setup Sytem and Degrees of Freedom with a formatted text file.
The topology file should be in a simple pipe-delimited format:
All filenames are relative to the paths specified in the constructor. These are the fields you can enter:
component_name: Name of the component (chain). Serves as the parent hierarchy for this structure.domain_name: Allows subdivision of chains into individual domains. A model consists of a number of individual units, referred to as domains. Each domain can be an individual chain, or a subset of a chain, and these domains are used to set rigid body movers. A chain may be separated into multiple domains if the user wishes different sections to move independently, and/or analyze the portions separately.fasta_fn: Name of FASTA file containing this component.fasta_id: String found in FASTA sequence header line.pdb_fn: Name of PDB file with coordinates (if available). If left empty, will set up as BEADS (you can also specify "BEADS") Can also write "IDEAL_HELIX".chain: Chain ID of this domain in the PDB file.residue_range: Comma delimited pair defining range. Can leave empty or use 'all' for entire sequence from PDB file.pdb_offset: Offset to sync PDB residue numbering with FASTA numbering.bead_size: The size (in residues) of beads used to model areas not covered by PDB coordinates. These will be automatically built.em_residues: The number of Gaussians used to model the electron density of this domain. Set to zero if no EM fitting will be done. The GMM files will be written to <gmm_dir>/<component_name>_<em_res>.txt (and .mrc)rigid_body: Number corresponding to the rigid body containing this object. The number itself is used for grouping things.super_rigid_body: Like a rigid_body, except things are only occasionally rigidchain_of_super_rigid_bodies For a polymer, create SRBs from groups.The file is read in and each part of the topology is stored as a ComponentTopology object for input into IMP::pmi::macros::BuildModel.
