Here are the steps that I used:

1.  trjconv -pbc whole -dump 37.875
2.  trjconv -pbc nojump
3.  trjconv -center
4.  g_select to make an index containing the atoms of interest
5.  trjconv to extract coordinates

Regardless of whether step 1 is used or not, the resulting coordination
shell configuration is not complete in the sense that it looks like the
figure I posted previously.  In all steps, I used the same .tpr file...is it
possible that I need to generate a new one after step 1?


1. trjconv -center -pbc mol -dump 37.875

As long as you're choosing an appropriate index group here (i.e., the single solute molecule of interest), you should not need any further invocations of trjconv before extracting coordinates. Pop open the resulting coordinate file in your favorite visualization software and verify. It should be very obvious if it worked as expected.

2. Make selection
3. Extract
