Subject: leap problem about periodic boundary box

Dear AMBER users

 Recently, we want to do very large size protein MD
by using sander5.0, and we are in difficulties for making
TOP & CRD files in xLeap in AMBER 5.0.
 When I edited protein files in xLeap, I needed to set
[90Ang. * 90Ang. * 130Ang.] size of periodic boundary box,
but I can't do it. xLeap recognized
not [90Ang. * 90Ang. * 130Ang.]
but [90Ang. * 90Ang. * 30Ang.].

Question
1. Does anyone have any knowledge to solve this problem
  of settin periodic boundary box size?
2. If I can solve this problem, does xLeap output
  TOP & CRD files over 999,999 atoms ?

thanks in advance
