Function

   Back translate a protein sequence

Description

   backtranseq takes a protein sequence and makes a best estimate of the
   likely nucleic acid sequence it could have come from. It does this by
   using a codon frequency table. For each amino acid, the corresponding
   most frequently occuring codon is used in the construction of the
   nucleic acid sequence.

  Codon usage table name

   backtranseq reads in a data file containing the codon frequency
   tables. The default codon frequency table is 'Ehum.cut' - the human
   codon frequency table. It is important to use a codon frequency table
   that is appropriate for the species that your protein comes from. See
   the Data Files section below for more details on these files.

Usage

   Here is a sample session with backtranseq

   Note that this is a human protein and so the default human codon
   frequency file is used ie. is not specified


% backtranseq 
Back translate a protein sequence
Input (gapped) protein sequence: tsw:opsd_human
(gapped) nucleotide output sequence [opsd_human.fasta]: 

   Go to the input files for this example
   Go to the output files for this example

   Example 2

   This uses a drosophila sequence and codon table.


% backtranseq -cfile Edrome.cut 
Back translate a protein sequence
Input (gapped) protein sequence: tsw:ach2_drome
(gapped) nucleotide output sequence [ach2_drome.fasta]: 

   Go to the input files for this example

Data files

   The codon usage table is read by default from "Ehum.cut" in the
   'data/CODONS' directory of the EMBOSS distribution. If the name of a
   codon usage file is specified on the command line, then this file will
   first be searched for in the current directory and then in the
   'data/CODONS' directory of the EMBOSS distribution.

   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

Notes

   None.

References

   None.

Warnings

   None.

Diagnostic Error Messages

   "Corrupt codon index file" - the codon usage file is incomplete or
   empty.

   "The file 'drosoph.cut' does not exist" - the codon usage file cannot
   be opened.

Exit status

   This program always exits with a status of 0, unless the codon usage
   table cannot be opened.

Known bugs

   None.
