Command usage

usage: pdbqtprep [-h] [-i INP] [-p PDBFILE] [--pdbid PDBID] [--url URL] [-o OUTBASENAME] [--add-atoms {all,heavy,hydrogen,none}] [--keep-heterogens {all,water,none}]
                 [--replace-nonstandard] [--add-residues] [--remove-chains REMOVE-CHAINS] [--ph PH] [--seed SEED] [--ligid LIGID] [-v]

protein and ligand coordinate files from a complex pdb file

options:
  -h, --help            show this help message and exit
  -i INP, --inp INP     yaml style input file, overwriting argument values (default: None)
  -p PDBFILE, --pdbfile PDBFILE
                        input PDB file (default: None)
  --pdbid PDBID         PDB id to retrieve from RCSB (default: None)
  --url URL             URL to retrieve PDB from (default: None)
  -o OUTBASENAME, --outbasename OUTBASENAME
                        basename of output PDB and PDBQT files (default: output)
  --add-atoms {all,heavy,hydrogen,none}
                        which missing atoms to add: all, heavy, hydrogen, or none (default: all)
  --keep-heterogens {all,water,none}
                        which heterogens to keep: all, water, or none (default: all)
  --replace-nonstandard
                        replace nonstandard residues with standard equivalents (default: False)
  --add-residues        add missing residues (default: False)
  --remove-chains REMOVE-CHAINS
                        specify list of indices or IDs of removing chains (default: None)
  --ph PH               the pH to use for adding missing hydrogens (default: 7.4)
  --seed SEED           Random seed (default: None)
  --ligid LIGID         Ligand ID in PDB file (default: None)
  -v, --verbose         Print verbose output (default: False)

Exmaples of command line usage

pdbqtprep --pdbid 3POZ --ligid 03P -o 3POZ --add-atoms all --keep-heterogens none --replace-nonstandard --add-residues --ph 7.4

Exmaples of yaml input usage

Prepare input yaml file input.yml:

pdbid: '3POZ'
ligid: '03P'
outbasename: '3POZ'
keep-heterogens: 'none'
add-atoms: 'all'
replace-nonstandard: True
add-residues: True
ph: 7.4
ignore_terminal_missing_residues: True
verbose: True

Then, run pdbqtprep in command line:

pdbqtprep -i input.yml

You can get protein models (3POZ_pro.pdb, 3POZ_pro.pdbqt) and ligand models (3POZ_lig.mol, 3POZ_lig.pdbqt).

Keywards of yaml file are the same in the name of command line options.
See above explation of command line options.
