## Function

Display a DNA sequence with 6-frame translation and ORFs

## Description

sixpack reads a DNA sequence and writes an output file giving out the forward and reverse sense sequences with the three forward and (optionally) three reverse translations in a pretty display format. A genetic code may be specified for the translation. There are various options to control the appearance of the output file. It also writes a file of protein sequences corresponding to any open reading frames that are larger than the specified minimum size: the default of 1 base shows all possible open reading frames.

## Algorithm

The program takes the following steps:

     The nucleic acid sequence is read in.
     The required genetic code is read in from the EGC* data files.
     The three forward and three reverse translations are created.
     The name and description are written to the ouput display file.
     Any required regions to be changed to upper case are changed.
     Any required regions to be highlighted in HTML colour tags are changed.
     The reverse sense sequence is placed below the forward sequence.
     The forward translations are placed above the sequences.
     The reverse translation are placed below the sequences.
     The display is written out, split at the ends of lines.
     Any ORFs that are longer than the specified minimum size are written to the output sequence file.

## Usage

## Data files

EMBOSS data files are distributed with the application and stored in the standard EMBOSS data directory, which is defined by the EMBOSS environment variable EMBOSS_DATA.

To see the available EMBOSS data files, run:

    % embossdata -showall

To fetch one of the data files (for example 'Exxx.dat') into your current directory for you to inspect or modify, run:

    % embossdata -fetch -file Exxx.dat

Users can provide their own data files in their own directories. Project specific files can be put in the current directory, or for tidier directory listings in a subdirectory called ".embossdata". Files for all EMBOSS runs can be put in the user's home directory, or again in a subdirectory called ".embossdata".

The directories are searched in the following order:

- . (your current directory)
- .embossdata (under your current directory)
- ~/ (your home directory)
- ~/.embossdata

The Genetic Code data files are based on the NCBI genetic code tables. Their names and descriptions are:

EGC.0
  Standard (Differs from GC.1 in that it only has initiation site 'AUG')
EGC.1
  Standard
EGC.2
  Vertebrate Mitochodrial
EGC.3
  Yeast Mitochondrial
EGC.4
  Mold, Protozoan, Coelenterate Mitochondrial and Mycoplasma/Spiroplasma
EGC.5
  Invertebrate Mitochondrial
EGC.6
  Ciliate Macronuclear and Dasycladacean
EGC.9
  Echinoderm Mitochondrial
EGC.10
  Euplotid Nuclear
EGC.11
  Bacterial
EGC.12
  Alternative Yeast Nuclear
EGC.13
  Ascidian Mitochondrial
EGC.14
  Flatworm Mitochondrial
EGC.15
  Blepharisma Macronuclear
EGC.16
  Chlorophycean Mitochondrial
EGC.21
  Trematode Mitochondrial
EGC.22
  Scenedesmus obliquus
EGC.23
  Thraustochytrium Mitochondrial

The format of these files is very simple.

It consists of several lines of optional comments, each starting with a '#' character.

These are followed the line: 'Genetic Code [n]', where 'n' is the number of the genetic code file.

This is followed by the description of the code and then by four lines giving the IUPAC one-letter code of the translated amino acid, the start codons (indicdated by an 'M') and the three bases of the codon, lined up one on top of the other.

For example:

    #
    # Differs from Genetic Code [1] only in that the initiation sites have been
    # changed to only 'AUG'

## Notes

An open reading frame is defined in this program as any possible translation between two STOP codons. Optionally, the beginning or end of a sequence may be counted as an ORF even if it's less than the minimal ORF size or (end only) lacking a STOP codon. See the -firstorf and -lastorf options.
