AMBER: energy plot in minimization

   There is something rare in the plot of the energy when doing a
minimization. At first the energy oscilates and then there is an abrupt
decrease when the method changes. Afterwards, the energy goes up. This rise
keeps on and then it seems to arrive to a plateau.
I will not do a normal mode analysis, but I donīt understand why it
Another doubt is to know if the convergence criterion is achieved or not.
Perhaps the anwser is that the ending has less steps than "maxcyc"
