[gmx-developers] Thought on gmx distance

I thought I would share a bit of feedback on the new implementation of g_dist.
First off, I love the flexibility in the selections now, so that's great. The
only problem is that gmx distance does not behave like the other tools.
Specifically, no list of available index groups is printed (default or
otherwise, when using -n index.ndx). I found that simply by pressing Enter when
prompted for a selection, I can get a list of available groups, but that's not
documented anywhere that I could find. It was sort of a random guess when I
stared at the screen and said, "where are my groups?"
So the suggestion I have is that gmx distance should act like the other tools
and print a list of available groups. That way, we don't force the user to have
to quit the program to refer to the index file or open up a new terminal and
then move back and forth. I don't know if there's some technical reason why
this isn't done already, but I thought I'd throw it out there. Without the
listing, I think there's an unnecessary barrier to use of the powerful selection
If I've missed something obvious in using gmx distance, please let me know; I'm
still getting used to the new setup of things!
