Yes, I just checked to verify that the refc is the same (in case there
was an error in my script). They are identical. I also did a careful
comparison of energies between the first step of md2_NPT and the last
step of md1_NPT. The only notable differences are in the restraint
energy and the potential energy (presumably because of the major
change in the restraint energy). I should note that the single-step
output md2_NPT run uses a Langevin thermostat, while the md1_NPT run
uses Berendsen temperature control. However, I have seen roughly the
same output using both thermostats for md2. Now I am quite puzzled.
Any suggestions on what I might check next?
Thanks,
Sally
