 [Apbs-users] what is "-pad integer Num. of pad grid points" ?

Thanks a lot.I look forward to your reply at your earliest convenience. Thank you very much and best wishes from Zurich, Switzerland.

What is the difference between 1 and 2? Thanks a > lot. > The pad flag simply adds a buffer to the region surrounding the region of interest (by expanding the min/max bounds). The grid bounds are then modified according to: min = grid_min - pad * grid_spacing - kludge max = grid_max + pad * grid_spacing + kludge Where the kludge is inconsequential for the purposes here. A pad value of 1 will add one grid spacing to the x, y, and z min/max bounds. A pad value of 2 will add grid spacings and so on... Hope that helps, Dave David W.
