Hello,
I have been doing some checking and am a bit puzzled by significant
differences in volume/minmax values for my system as I prep it.
Shown below is a list of the dimensions from VMD, while my NAMD logs show
a constant value of 923636.6390. As you can see there is a significant
difference between ^^^^^^^^^^^ and 964243.
Any ideas?
Brian
