[gmx-users] number of water molecules along z

[Jagannath Mondal]

Dear Gromacs-users

  I need to compute the time profile of number of water away from a
membrane center along z direction. However trjorder -nshell -r 0.6 will
give me the number of waters along radial direction.
  there is an option in trjorder -z . but that just orders molecule along
z. but does not let one calculate water number along z at a cutoff distance.
Is there any other ways of getting it?
