What is the unit and meaning of the eigenvalue in NMWiz of VMD (ProDy) ?

Hello.

I am now focusing on finding natrual frequencies of biomolecules using NMWiz in VMD

In VMD TkConsole, the function 'prody eda' can yield the eigenvalues using PDB and DCD files.

Following the ProDy manual, the unit of the eigenvalues seem to be [angstrom^2].

That is correct?

And additionally, How can I get the natural frequencies?

is it sqrt(kB*temperature/(eigenvalue*molecuarWeight))

Do I use the option of NAMD: harmonic restraint?

Hi~ I'm a graduate student studying MD simulation. When they use SMD simulation, many researchers used the option: harmonic restraint. Why do they use the option? What does it mean?

fatal error

When I tried to energy minimization my system, I got fatal error as below. Fatal error: Atomtype opls_116 not found Although I've already added this line: ; include water #include "oplsaa.ff/spc.itp" to [molecultype] directive in my topology.
