Your scheme will not work because the structure in the .tpr file is the same as
in your em_out.gro, which you claim to be broken.  I'm assuming em_out.gro
refers to your structure following energy-minimization?  And if so, I'm
wondering what you've done that's left a broken molecule following EM.  Is your
em_out.gro whole?
