Here post your question
I want to use the gmx hbond command to analyze the hydrogen bond of a box by region in the Z direction. For example, the box size is 5nm × 5nm × 5nm, and I want to divide it into three regions z=0~ 1.5nm, 1.5~3.5nm, and 3.5~5.0nm in the Z direction. How do I calculate the hydrogen bond for each of these three regions by gmx hbond? How do I select the specified z-axis range in gmx hbond?
