Hi,
I can write out a psf and a pdb in charmm and convert to NAMD formats,
sure. But the psf does not contain the velocities, so the velocities will
need to be re-initialized in NAMD, which will, thus, lead to an entirely
new simulation. Am I wrong ?

Is it possible for you to use charmm for writing out a crd/psf file pair for the final state of your charmm simulation? If so, you can continue by converting the charmm crd/psf pair to a NAMD pdb/psf pair using the two scripts at
