That's expensive. mdrun goes to great lengths to speed up computing
billions of distances. <br>

<br>
Yes you can. Even if you think you need data from every frame, you
probably don't because they're correlated with each other, and at
the very least you can do a pilot study on a frame every 100ps or
every nanosecond before committing to one on all the frames.<br>

You are not likely to get a better solution if you only describe
your attempt, rather than describe the objective. Asking "how do I
hammer harder?" if you're hammering a screw makes it impossible to
get the correct solution "Use a screwdriver".<br>

No. If it will take too long, you need to reduce your number
of frames (trjconv), or the number of atoms (also trjconv),
or some such.<span class="HOEnZb"><font color="#888888"><br>
