Yes, you can use "measure minmax" in VMD to get the box dimensions. You should preferably use cell basis vectors a little larger than the the numbers you get from the "measure minmax" command, to prevent 'clashes' between water molecules between your simulation system and the images (although minimization might solve these). See also the example of the config-file with periodic boundary conditions from the tutorial files (ubq_wb_eq.conf and p.20 in the tutorial).

How does one determine the cell basis vectors when setting up a simulation
in a periodic box? I have used the "measure minmax" command to obtain the
dimensions of the box. Am I correct to assume that these are the numbers I
Thanks for any help!
