I want to calculate the spatial distribution function in a system containing Li+ and Cl- in aqueous solutions, but some programs I used didn't help me much. In gromacs the graphics are a little rough, and in travis (which I liked the most) it is not possible to calculate this analysis when you have only one reference atom. I've tried to create a pseudo molecule using advanced mode, but the results weren't very plausible. If anyone knows any other program I can use to calculate these spatial distributions, I would be very grateful.
