HI, David, thanks for your advise. I remove the bond angle force and get same result. It is really strange. If I set +5 on all the 24*24 grid, I just get a inverted distribution and if I set 0 on all grid, I will get a uniformed distribution. It is like that 27 regions are force to have zero cmap potential. I cannot attach figure due to size limit the list. I have sent the figure to you directly.
