One of my issues is now solved. As you guessed, the PBD was in an improper format.
After solving this small issues, I read about the need for an lipids.itp and pope.itp file. I found these tutorial (link below) for the itp file construction. Can I adept these steps for the construction of correct itp files for POPE lipids? In a last step , I would exchange all parameters with the right ones from a CHARMM FF. Right now, I in fear of conduction terrible mistakes. Is there a much more common way to solve this task ?
