Dear CP2K group,<div><p>I am doing some GAPW MP2 calculations on a single water
molecule to familiarize myself with CP2K. I am wondering if there is a way to
NOT correlate the O(1s) electrons when doing MP2. I have looked through the
online manual (v8.1) and was not able to find a keyword for that.</p>
<p>Thank you for the help!</p><p>Kristina</p></div>
