# coot-available-comp-id(1)

## NAME

coot-available-comp-id

## SYNOPSIS

coot-available-comp-id \[comp-id\|comp-id-prefix\]

## DESCRIPTION

coot-available-comp-id is used to find an available comp-id for a new ligand. A comp-id prefix can be either one or two characters.

If a 3-character comp-id (e.g. XYZ) is given then coot-available-comp-id will either say

INFO:: comp-id XYZ is available

or

INFO:: comp-id XYZ is not available

A comp-id-prefix will result in a list of the available comp-ids with the given prefix.

## NOTES

The Coot package needs to be compiled with the CCP4 SRS for this to give useful output.
