[gmx-users] ERROR :: Atomtype LC3 not found : KALP-15 in water tutorial

[Seketoulie Keretsu]

Dear Expert,

While doing the KALP15 in DPPC tutorial, I came across this error. I have
tried google search for solutions but couldn't resolve it. Would appreciate
if you would kindly let me know how to move forward:
INPUT COMMAND: gmx grompp -f minim_inflategro.mdp -c system_inflated.gro -p
topol.top -r system_inflated.gro -o system_inflated_em.tpr

OUTPUT ERROR:
ERROR 1 [file dppc.itp, line 7]:
  Atomtype LC3 not found

Full error message:

 gmx grompp -f minim_inflategro.mdp -c system_inflated.gro -p topol.top -r
system_inflated.gro -o system_inflated_em.tpr

  With Verlet lists the optimal nstlist is >= 10, with GPUs >= 20. Note
