Thanks a lot for the quick reply. I want to position restrain the head group
atoms of CG DSPC but I am not sure about the head group molecules in DSPC.
Can you please tell me how to figure out the head group atoms or molecules.
Also, when you say co-ordinate file then you mean .itp file for the lipid
