## Function

Extract CDS, mRNA and translations from feature tables

## Description

The feature table of sequence database entries often have sections like this:

This specifies that the coding sequence for the gene is constructed by joining several sections of code, many of which are in other entries in this database.

    FT   CDS             join(U21925.1:818..987,U21926.1:258..420,

    FT                   U21930.1:895..1014,516..708)

or:

This specifies that the messenger RNA sequence for the gene is constructed by joining several sections of code, many of which are in other entries in this database.

    FT   mRNA            join(M88628.1:1006..1318,M88629.1:221..342,

It is often a tedious and error-prone job to extract the several sections of these sequences from the database entries and to join them together to construct the indicated finished sequence.

coderet does this job for you.

You specify the sequence containing the feature table and it extracts the required CDS, mRNA and/or protein sequences specified by this feature table. If any sequences are in other entries of that database, they are automatically fetched and incorporated correctly into the final sequence.

The translations are not made from the coding sequence, they are extracted directly from the translation sequence held in the feature table.

## Usage

Here is a sample session with coderet

To extract all of the CDS, mRNA, non-coding and the protein translations:

    % coderet
    Extract CDS, mRNA and translations from feature tables
    Input nucleotide sequence(s): tembl:x03487
    Output file [x03487.coderet]:
    Coding nucleotide output sequence(s) (optional) [x03487.cds]:
    Messenger RNA nucleotide output sequence(s) (optional) [x03487.mrna]:
    Translated coding protein output sequence(s) (optional) [x03487.prot]:
    Non-coding nucleotide output sequence(s) (optional) [x03487.noncoding]:

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

Example 2

To only extract the mRNA sequence:

    % coderet -nocds -notranslation -norest
    Extract CDS, mRNA and translations from feature tables
    Input nucleotide sequence(s): tembl:X03487
    Output file [x03487.coderet]:
    Messenger RNA nucleotide output sequence(s) (optional) [x03487.mrna]:

## Output file format

The output is a sequence file containing any CDS, mRNA and protein translation sequences as specified by the feature table of the sequence(s).

One or more of CDS, mRNA, translation can be excluded from the output by using the appropriate qualifiers to the program (i.e. -nocds, etc.)

The ID names of the output sequences are constructed from the name of the input sequence, the type of feature being output (i.e. cds, mrna, pro) and a unique ordinal number for this type to distinguish it from others in this sequence. The name, type and number of separated by underscore characters. Thus the second CDS feature in the sequence 'HSXYZ' would be named 'HSXYZ_cds_2'.

The translations are not made from the coding sequence, they are extracted directly from the translation sequence held in the feature table.
