Ah, good to know, thanks for the info.

I realized that I used top_all27_prot_lipid to setup the membrane and since O3 referes to OHL in toppar_all27_lipid_cholesterol and OHL is type 165 in top_all27_prot_lipid I think I have found the mistake.

I'll try to append the all27_na to all27_prot_lipid and regenerate the RNA psf from the PDB (or change types... python will come i handy here)
