[gmx-users] atoms

[Dinesh Pinisetty]

Hi all,
    I mean what does atom typr 'LO' or 'LOM' stand for.In DPPC we have
CH2,CH3,P,N,O atom types when i have seen its structure but in Dr.Tielman's
site I have downloaded lipid.itp and dppc.itp files wherein we have 12 atom
types like 'LO' 'LOM' 'LC3' 'LC2' etc.Full form means,I does not mean
charges,bond types etc I need what exactly they stand for.As a very
beginner I just want to understand atom types present in the file
properly.When I see DPPC structure I have seen 5-6 atom types but in the
file I have 12 atom types or so.
  Please tell me what they stand for and why there is a difference in the
atom types between the structure and in the file.
I hope you got what I mean.Thanks a lot in advance..........
Dinesh.

What do you mean by 'full form'? The [atomtypes] section defines the mass,
LJ parameters and charge. What else is there to know?
