| descseq

## Function

Alter the name or description of a sequence

## Description

Most sequence formats allow, at the very minimum, a name for the sequence and some comments to be stored in the sequence file.

Rather than using an editor to alter the name or the comments, descseq allows you to simply change them and write out a new file with the changes in and the sequence left unaltered.

The default action is to replace the existing name or description with your new one, but by using the qualifier '-append' what you enter is appended to the existing name or description.

Note that if you append to a description, no space is inserted by default bewteen the existing description and your appended text. You have to put in a space yourself if you require one.

## Usage

Here is a sample session with descseq

Set the name of a sequence to "myclone23"

    % descseq -seq dna.text -out clone23.seq -name "myclone23"
    Alter the name or description of a sequence.

Example 2

Set the description of a sequence to "This is my clone number 244"

    % descseq -seq dna.text -out xy24.seq -desc "This is my clone number 244"
    Alter the name or description of a sequence.

Go to the output files for this example

Example 3

Append some text to the description of a sequence

    % descseq -seq dna.text -out est4.seq -desc " (submitted)" -append
    Alter the name or description of a sequence.
