In its current form, NAMD does not perform NMA. If you own a CHARMM
license, then I'd suggest you to use it for such purpose.
One more thing: NMA is a very expensive way to calculate the entropy
(you need to perform energy minimization of N conformations taken from
your trajectory, for example), so you also might find useful the
quasi-harmonic approximation using a weight-mass covariance matrix.
I've done MMPBSA using NAMD to calculate the MM energies, APBS to
calculate the solvation contribution and the quasi-harmonic
approximation to calculate the entropic term, and so far it has worked
