<br>
What is the easiest and fastest way to get the number of H bonds on every frame of a large trajectory (&gt;10 000 frames) and print it to a file?
<br>
The hbonds command does not seem to work with the perframe command and displaying the whole trajectory to run a per-frame script is quite slow.<o:p></o:p></span></p>
