ptraj

Hello,

I compiled ptraj on a SGI R10000 machine and was trying to simply convert
a CHARMM trajectory (binary format) produced on the same machine to a
AMBER trajectory. I am getting a segmentation fault (core dump) so was
hoping I could get some help.

Here is what I am doing and it seems to read the CHARMM trj fine

$ptraj nad_gen1.psf ptraj.in

PTRAJ: Processing input file...
       Input is from file ptraj.in

PTRAJ: trajin nad_dyn1.trj 1 200 1

PTRAJ: trajout nad_dyn1.traj trajectory nobox

PTRAJ: go

PTRAJ: Successfully read the input file.
       Coordinate processing will occur on 200 frames.
       Summary of I/O and actions follows:

INPUT COORDINATE FILES
  File (nad_dyn1.trj) is a CHARMM trajectory in big endian binary format
    representing 200 sets
  NFILE = 200 ISTEP = 1000 NINTV = 1000 NSAVC = 200000
NSAVV = 0
  NDEGF = 178 NFREA = 0 DELTA = 0.0205 QCRYS = 0
QDIM4 = 0
  VERNU = 27 NATREC= 70 NFREAT = 70
  Dumping the title:

OUTPUT COORDINATE FILE
  File (nad_dyn1.traj) is an AMBER trajectory

ACTIONS

Processing CHARMM trajectory file nad_dyn1.trjSegmentation fault (core
dumped)

*******************

The AMBER trajectory file is created but with no data.
I'm probably missing something simple but have tried a few permutations
with no luck. Any help would be appreciated.

Thanks,
