# pdb\_chainbows(1)

manual page for pdb\_chainbows 2.5.1

## NAME

pdb\_chainbows - manual page for pdb\_chainbows 2.5.1

## DESCRIPTION

pdb\_chainbows File not found or not readable: '--help'

Renames chain identifiers sequentially, based on TER records.

Since HETATM records are not separated by TER records and usually come together at the end of the PDB file, this script will attempt to reassign their chain identifiers based on the changes it made to ATOM lines. This might lead to bad output in certain corner cases.

### Usage:

-

  python pdb\_chainbows.py \<pdb file\>

### Example:

-

  python pdb\_chainbows.py 1CTF.pdb

This program is part of the \`pdb-tools\` suite of utilities and should not be distributed isolatedly. The \`pdb-tools\` were created to quickly manipulate PDB files using the terminal, and can be used sequentially, with one tool streaming data to another. They are based on old FORTRAN77 code that was taking too much effort to maintain and compile. RIP.
