Dear All I am trying to prepare a solvation box of chaps. After generating .itp and .gro at ProDrg and thorough check of charges, I started with a box size of 6x6x6. Energy minimization, simulated annealing (Cooling under high pressure and again heating at normal pressure) as well as final equilibration ran smoothly. But finally I get a box where all water molecules get accumulated in two three small region within the box and all chaps molecules gets accumulated in another small regions.I wanted near random uniform distribution of chaps in water. Any help from user, where I am wrong and what should I do. Shahid nayeem
