[gmx-users] gmx select and gmx trjconv or gmx density

[Dan Gil]

Hi,

I am trying to select particles that are z < 20 and z > 10 as a function of
time.

I think I used gmx select correctly and generated an index file with group
names like "(z_<_.8_f2882_t23056.000)"

Now I am unsure how I use this index file for gmx trjconv or gmx density.
Does anybody have some advice?

Thanks in advance.

Best Regards,
