the first thing to consider in this kind of circumstance is whether you have
ever seen such an application reported in the literature, or if just
exploring the method itself will be a research project. if you have similar
papers, then they will guide you until you reach technical problems, at
which point you might post them here. If there is no previous example in the
literature, perhaps the best approach is to try it out and see what happens,
and if you run into technical problems post them here.

almost certainly, minimization will not do what you need. TMD for large
structure changes should be considered a very advanced method to be
undertaken after you are very familiar with normal MD simulations, then the
TMS will be a step up from those. right now your question needs to be a
little more specific about your goals and current knowledge and then we can
try to help with the technical questions (but it is very hard to ask in
email for someone to give a full explanation of how to do something
complicated).
good luck
