EMBOSS: backtranseq manual

backtranseq

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 sequence: tsw:opsd_human
Output sequence [opsd_human.fasta]:

Example 2

This uses a drosophila sequence and codon table.


% backtranseq -cfile Edrome.cut 
Back translate a protein sequence
Input sequence: tsw:ach2_drome

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.

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.
