  Thanks for your reply.
In order to check the warning of grompp after scaling up I ran grompp again 
without -maxwarn:

grompp -f minim.mdp -c system_inflated.gro -p topol.top -o em.tpr
WARNING 1 [file minim.mdp]:
   The sum of the two largest charge group radii (3.840099) is larger than 
rlist (1.200000).

Do I need to change the minim.mdp settings? Visualizing the system doesn't show 
any odd result!
Would you mind helping me?


Likely you did not correctly remove the periodicity of the DPPC membrane before inflating so you have fragmented molecules somewhere. Go back and fix it according to the instructions provided in the tutorial.
