Hi,
I don't think VMD can do that job, directly. Why don't you used Molden?
To visualize vibrational modes with VMD, I usually generate a serie of
snapshots in PDB format t_1,t2,...,t_n from the equilibrium structure by
using the algorithm:
x(t_n) = x_eq + eive_i*cos(omega_i*t_n)
where eive_i and omega_i are the eigenvetor and frequency of the mode
which you would like to visualize, respectively.
Then I put all of these snapshot in one file and VMD can read this file
and vizualize a nice movie.
Phuong.
