Thank you very much, guys. What I wanted actually was a software that gives the formal charge looking at different axis of my model instead of particular residues. Then, placing the center of my model at coordinates 0,0,0, I would be able to see the sum up of charges at +/- x, +/-y and +/-z. I will take a look on the sites and in chimera.

Anyway, I can see it below now that I have started typing this reply, and advice is excellent. My answer to Rafael's question would be to look at apbs: https://www.poissonboltzmann.org/ This gives you a map of the potential. It's a while since I dabbled with it, but I remember using it and it was all pretty workable as a standalone program, even for an electrostatics non-specialist. You might need to do some scripting to sum up charges, etc, though. Good luck. Jon.C.

You have to enable this option in the surface drawing panel. I've used this option quite often. There may be a similar option in chimerax by now. My 2p.

I hope you are having a great break and still eating the leftovers of your Xmas turkey. I wonder if there is any software that could provide me numbers regarding the formal charge of different sides of my structure. Although I can clearly see that one face of it is pretty red, I would like to know “how much” red it is.
