Thanks Justin for the quick reply. by the way after i solvated the protein with water and i change the amount of the protein that i want for example 8 and the amount of water that already in is 20453.But after i proceed with grompp the result shows that my .top file have different number of configuration with the solvation, .gro file. In addition when i view the file with vmd it still show only one protein and not the exact amount that i want.Well i'm kinda lost because after pdb2gmx for the single molecule and i separate the topology file with the .itp protein,the itp file still consist of 1 protein not 8 proteins right?
