Give it time. One week is usually not sufficient time for carbonation. Depending on the OG of the brew, and the yeast itself, carbonation times can vary. If you brewed a 1.090 monster, it would take a lot longer to carbonate than would a 1.035 brew.

Give it another 2 weeks. The general rule of thumb is 3 weeks, but as it was already said, if you brewed a big beer, you will have to wait longer. Don't listen to recipe times, they are almost always wrong.
