Thank you Justin For  Your Previous reply

Finally Somehow I have  Adjusted  The Cut-Off  and  Grid Size and Inserted 
Protein in Lipid By Deleting some Lipid Molecules  MY Question is

                                                              1)  When I am 
Using inflategro  Perl  Script ,I need to Use Cut-off , Scaling Factor ,Grid 
size ,

Is there is Any Rule to Set up Suitable Factor (Aforesaid)  For my System ?


Please read the paper associated with the InflateGRO script.

2)  I need to Use Only  Protein Surrounded By Lipid Molecules . I Do not Want 
to use  genion tool to insert water .

Is it Possible ?  and  Is it Reasonable  To do Direct Minimization, 
Equilibration, Production MD  without Water ?


You can do EM without water, but trying to simulate a protein in a membrane in vacuum does not make sense. The force fields are not designed to be used in this way.
