Dear GROMACS users,
I have used g_hbond of version 4.5.2 to analyze number of hydrogen
bonds in water. I got the average number per time frame and number
of water oxygen atoms equal to 0.839. When I used g_hbond of version
4.0.7 I got 1.677, which is twice the former value. TIP3P model
predicts over 3 hydrogen bonds per one water molecule. I am a bit
puzzled. If I multiply the digit from version 4.0.7. by 2 I get the
expected number. That is why I supposed that the number of 1.677
means per one water oxygen and per one water molecule means 2x1.677
since two water molecules participate at one hydrogen bond.
However, I do not know yet if my interpretation is correct and how to
interpret the number obtained by version 4.5.2.
I would appreciate any help. Thank you in advance.
Try pulling the latest stable development version. This issue was
reported in 4.5.1:

but not fixed until after 4.5.3 was released:

Are people who are reporting this error using a triclinic boxes or
cuboid boxes. That information may help my bugfixing.
