Notes:  1. A similar webtool developed by lh3: http://lh3lh3.users.sourceforge.net/fasta.shtml
        2. When you search, you can use RegExp supported by Perl.
        3. When you extract the sub|full-seq, you can use RegExp in the Name|ID (-n Name|ID) to match more than one record. But the RegExp must be in the double quotation marks, for example, "chrd+".
        4. The RegExp use case-sensitive mode.
