Do the xaver.pdb and the md.trr correspond in terms of atom numbers?
The JACOBI error has to do with the fitting. The 'broken molecule'
thing is a warning, issued because you give a .pdb file which does not
contain information regarding connectivity, which coulod otherwise be
used to make broken molecules whole. But you shouldn't have broken
molecules if you didn't run trjconv on the trajectory with certain the
