Hi Norman,
Thanks for your response. The reason I wish to equilibrate the system at
each temperature is because it contains lipids and abrupt temperature
changes destroy the bilayer. Would minimization help in this regard or do
you have any other suggestions?
P.S. I'd appreciate if you could provide me with the modified code you
mentioned.
Regards,
Horia
