I would like to run CP-corrected MP2 calculations. The current version of PSI4 will run calculations for A, B, A+ghostB, B+ghostA, and AB. The old version I used before only calculated A+ghostB, B+ghostA, and AB. How can I make the current version of PSI4 only do calculations for A+ghostB, B+ghostA, and AB? My input is shown below. Thanks.
