yes that is correct. If you want to see it with the protein in the middle
you can use the pbctools plugin commands in VMD.
For instance, in the TKConsole, you could enter the following commands:
pbc unwrap
pbc wrap -centersel "protein" -center com -compound residue -all
I'm not actually confident you need to unwrap it first, but at any rate,
the above will work to shift where the periodic box is, such that you're
protein is now in the middle. It assumes that VMD already has the periodic
box values, which it should have automatically if you're loading an NAMD
DCD trajectory.
