How to combine OPLS-AA with Berger lipids? Links in tutorial dead

GROMACS version: 2022
GROMACS modification: No

Greetings! I would like to simulate a small molecule (described by OPLS-AA) interacting with a POPC bilayer (Berger lipids). However, the links in the GROMACS membrane tutorial (see below) that should lead to instructions on how exactly to combine these two force fields are dead, and I could not find these instructions in the forum or the mailing list archive. Could you please let me know where I can find the instructions on what steps I have to take to combine the OPLS-AA force field with Berger lipids?

Links are fixed. Sorry, guess it’s been many years since anyone wanted to look that approach up.

Thank you very much!
