NAME
        get_part - extract base, amino-acid, and other components in PDB
SYNOPSIS
        get_part [OPTION] PDBFILE OUTFILE
DESCRIPTION
        extract the different structural components, i.e., base, amino-acids
        and other, from a PDB file. Useful for handling each separately
        -n      nucleic acid (default)
        -l      only backbone atoms of nucleic acid
        -b      only base atoms of nucleic acid
        -x      nucleic backbone (without O1P/O2P) and base ring atoms
        -z      P and base ring atoms
        -p      protein
        -t      ligand (HETATM records)
        -w      delete WATER (H2O)
        -d      delete H atoms
        -h      this help message (any non-recognized options will do)
INPUT
        PDB file
        One-letter options can be in either case, any order and combined
