Hi John,

This is the format, first it comes with invariant commented headers,
then the grid size, origin, grid number, then finally the potential
value like this:

 # the following data is provided:
 # h, gox, goy, goz
 # xm, ym, zm
 # phi(1:xmymzm) in kcal/mol-e
 # mapping between (i,j,k) and phi index:
 # i + xm * ( j-1 + ym * ( k-1 ) )
 # obtaining coordinates: xg = gox + h*i;
 # yg = goy + h*j; zg = goz + h*k
 0.500000000000000 8.48434360032879 3.50733980000000 5.25667429967121
 63 85 79
 -0.685886647608785 -0.692272931164146 -0.698618767180744 [deleted]

I also put an example data package in
http://apple.sysbio.info/~mjhsieh/files/pbsa_potential.tbz, you can
open the structure with parm7/rst7 VMD options.

Thanks
