TMD is a technique originally proposed by Schlitter in which the simulated system
is slowly driven from its initial configuration to a predefined target configuration,
to study possible transition pathways. AFAIK, it functions such that
that the RMSD to the target structure gradually decreases (or if you like
the radius of the hypersphere around the target structure sampled by the
simulation steadily decreases).
It wouldn't be too difficult to implement in gromacs. In fact most of the
functionality is already present in the ED sampling module.
