It might be consistent with it, but it is never diagnostic of it. FWIW, I
have never seen an REMD study that attempted to address whether generalized
equilibrium was achieved.

g_energy to get the data for each replica, then your favorite analysis
package to form histograms, and graphing program to overlay the plots. The
histograms can be done with g_analyze.
