GENNUC(1)
NAME
- gennuc - Generate double-helical DNA or RNA structures
SYNOPSIS
- gennuc -t structure-type [ sequence-file ]
DESCRIPTION
- Gennuc generates a Protein Data Bank (PDB) formatted file of
coordinates on standard output representing double-helical
DNA or RNA structures built from standard base-pair
coordinates.
- Valid structure-type code s are:
- brl right-handed B-DNA in Langridge configuration.
- bra right-handed B-DNA in Arnott configuration.
- bls left-handed B-DNA in Sasisekharan configuration.
- ara right-handed A-DNA in Arnott configuration.
- arn right-handed A-RNA in Arnott configuration.
- apr right-handed A'-RNA in Arnott configuration.
- The base-pair input sequence is read from the named file or
standard input if no sequence-file is given. Valid codes
for DNA are A, T, C, and G (for adenine, thymine, cytosine,
and guanine). Valid codes for RNA are A, U (uracil), C, and
G. Either uppercase or lowercase characters may be used.
Invalid codes are noted, but otherwise ignored.
