No, but you do need to have Bioinformatics Toolbox installed and licensed.
The first of that you can check using the VER function; the latter you'll
want to speak to whomever maintains your license. If you're in charge of
maintaining your license, contact MathWorks Sales. If you're using the
Student Version it is available as an add-on product.
