mdrun will have written a 'confout.gro' file, containing coordinates and
velocities. While less accurate than a .trr file, still better than using
only coordinates and re-generate a Maxwell distribution of velocities!
(Come to think of it, mdrun should also have written a .trr file (regardless
of your .mdp file settings) with the first (i.e. starting) and last step of
the simulation. Did you throw away these files?)
