Dear professor:
   We simulated a pentamer protein with NAMD. I am confused about that some part of the pemtamer fluctuated in and out of the box when I viewed the trajectory in VMD. Then I dealed with pbctools in vmd and failed. The command used are at below.

package require pbctools
pbc wrap -all -compound res -center com -centersel all

  After this operation, all parts of the protein was centered. But there are errors in some of the structures. When I viewed the treated trajectory in VMD, the unrecognizable structure coordinates were generated.
  What can I do about this problem?
