Hi everyone,
I have done simulation for DNA with LaCl3 in water, and now I want to count
how many charges inside cylindrical with radius r (r:0->R) from DNA.
Could you tell me do GROMACS have any analysis tool can do this or how can
I do this?
(as in my photo, the small-dot are the ions La and Cl)
Thank you too much!
