I calculate the electrostatic potential of a protein with VMD
and APBS. I get a .dx file that I import in VMD. Why I don't
see dots in the whole volume of the box? I thought that the
electrostatic potential is calculated in 129x129x129
gridpositions counts. Then I calculated the electrostatic
potential by APBS alone and I got a dx file with 97x65x65
gridpositions counts. I represented these two files as
isosurfaces (red for isovalue -1 and blue for isovalue 1). The
isosurfaces of the two files are different. Can somebody tell
me why?
Thank you,
