Excellent. I will figure out how we should add patches to the program on
the website, thanks for catching this one.
As for the difference in the harmonic and quasi-harmonic approximations: I
don't know the specifics, but I believe the quasi-harmonic approximation
utilizes the covariance matrices (weighted by the mass of the particles) of
the systems and diagonalizes them to obtain the corresponding eigenvalues
and eigenvectors, wherein it treats the eigenvalues as vibrational
frequencies. Thus, it constructs a single matrix from all of the snapshots
(akin to PCA).
Normal Mode analysis, on the other hand, constructs the hessian matrix for
each (minimized) snapshot and diagonalizes that, obtaining the vibrational
frequencies and computing the entropy based on that in a manner similar to
the quasi-harmonic approach. However, the normal mode analysis is different
because only a single structure, theoretically located at a local minimum on
the potential energy surface well-approximated by a harmonic potential, is
used to calculate the entropy. The QH approach takes snapshots from all
sorts of local minima to construct the matrix, leading it to be quite
frame-dependent (i.e. it depends on the number of frames you have), and it
can take a very large number of frames to converge (and you will get a much
much larger value than nmode calculations). QH is faster because you only
have to do one diagonalization, and I believe (though I'm not sure!) that
the covariance matrix is quite faster to compute than the hessian which is
used for normal mode analysis (another difference I forgot to mention
explicitly above).
Hopefully this helped a little (I think the AmberTools manual has some
references under the "matrix" and "analyze matrix" keywords for ptraj). If
I made some fundamental errors in my explanation, someone please correct me,
I have not studied these in depth.
Good luck!
