Dear Lammps users and Developers,
I want to compute number of atoms in a region of simulation BOX.
I have defined a region and applying force on each atom in that region with addforce command using region keyword.
Is there any way so that I can get number of atom in that region in every step.
Thanks and regards,

What kind of region it is?

variable foo count(g1,r1)
and print the value of variable foo
