|   | descseq | 
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.
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. | 
Go to the input files for this example
Go to the output files for this example
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. | 
Go to the output files for this example

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.
