First, 200 snapshots is way too few to see much of anything from quasiharmonic
analysis, and enormously too few to use to compute an entropy. Second, the
structures should not ordinarily be minimized prior to quasiharmonic analysis:
the idea is to help in understanding the nature of the thermal fluctuations
that take place.
