Hi John,

Yes, I have run some of those simulations when I attended the NAMD
wokshop at Boston last year. What I am not sure is that whether the
tutorial parameter files includes the Brenner's hydrocarbon potential
for nanotubes. We didn't simulate the nanotube atoms in the tutorial
(all of them were fixed), we just simulated the water permeation through
them. I want to run simulations where I can stretch, pull, strain the
nanotube by applying external force.

Please let me know if the tutorial parameter file contains the brenner's
potential or else where can I find those files.

Thanks in advance.
Gaurav
