Hi,
  This tells me two things:
1) You're using loading the DCD with one of the older versions of VMD
   (which defaulted side lengths to 1.0, new version defaults to 0.0)

2) Your DCD trajectory was written by an older version of NAMD that didn't
   save periodic cell information in the DCD file.

It would be helpful to know the precise version of NAMD you're running,
since that'll tell me much more about the particular DCD style you're
working with. (the NAMD DCD output has changed a few times over the years...)
