# Program 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 is 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

Set the name of a sequence to "myclone23"

    % descseq -seq clone23 -out clone23.seq -name "myclone23"

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

    % descseq -seq xy24 -out xy24.seq -desc "This is my clone number 244"

Append some text to the description of a sequence

    % descseq -seq est.seq -out est4.seq -desc " (submitted)" -append

## Command line arguments

       Mandatory qualifiers:
      [-sequence]          sequence   Sequence USA
      [-outseq]            seqout     Output sequence USA

       Optional qualifiers:
       -name               string     Name of the sequence
       -description        string     Description of the sequence

       Advanced qualifiers:
       -append             bool       This allows you to append the name or
                                      description you have given on to the end of
                                      the existing name or description of the
                                      sequence.

       General qualifiers:
      -help                bool       report command line options. More

                                      qualifiers can be found with -help -verbose
