I am pretty sure that I never implemented the binary restrt into ptraj;
mostly our group never uses these except for NMODE calculations.
Regarding the AMBER9 error, I also cannot be of much help here. It should
be rocket science to add this support to ptraj and we'll look into the
issue in AMBER9...
