Function

Alter the name or description of a sequence

Description

descseq reads a sequence and writes it to file but with a different name and / or description. All other records including the sequence itself are left unaltered.

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.

Example 3

Append some text to the description of a sequence


% descseq -seq dna.text -out est4.seq -desc ' (submitted)' -append

Input file format

descseq reads a normal sequence USA.

Input files for usage example

Notes

Most sequence formats allow, at the very minimum, a name for the sequence and some comments to be stored in the sequence file. descseq let's you change the sequence name and / or description, and is far more convenient and less error-prone than using the editor for editing.

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.

Exit status

It always exits with status 0.
