"so please provide me the code as early as possible."

That's really not what we do here. Saying you're new to perl is good, showing no effort, a specification for the software you're supposed to deliver then asking for the whole thing to be done for you isn't so good.

Since you're new to perl and this site I suggest you take the time to read and understand the following:

• PerlMonks for the Absolute Beginner
• perlintro
• http://learn.perl.org
• http://perldoc.perl.org
• The Tutorials section of this site, including Perl and Bioinformatics.

If you have any questions about perl and programming, rather than just requests for people to do your work, let us know.
