Thanks for your help, Justin. I ran gmxcheck -c topol.tpr ("12284

now gmxcheck shows that the number of atoms in topol.tpr is 12284, but

You haven't really changed anything. The xtc-grps parameter defines
what was saved in the simulation. Setting it after the fact does not
affect the already-produced .xtc file. What you need is a .tpr file
that contains only TDR, so you would have to make modifications to your
.top in order to generate this TDR-only .tpr file.
Or use tpbconv - this is the "other" application for that utility.
