[gmx-users] About EM for Lipid Protein Tutorila

[vidhya sankar]

Dear Justin Sorry   for the inconvenience in the previous Mail .
I am Much obliged for your  Previous help
Now I  am following Your Lipid Protein Tutorial
 I am using DPPC128.pdb And I Have Downloaded the DPPC.itp and topol_DPPC.top When I run the energy Minimization (em.mdp Downloded form your  website) for the this Lipid I have got Following error 

Warning: 1-4 interaction between 1256 and 1259 at distance 3.831 which is larger than the 1-4 table size 2.200 nm
These are ignored for the rest of the simulation
This usually means your system is exploding,
if not, you should increase table-extension in your mdp file
or with user tables increase the table size

 I am using Default .itp , .top (Down Loaded from website quoted by you)  and Dppc.gro (created by Editconf tool)

Why this error comes ? 
I Have not manually constructed  .top for lipids May be there are several discussion about this error in Mailing Archive .  
Here You Have not mentioned this type of error in your website  Where have i committed Mistake? 

Thanks In Advance
