I am a new user to MMTK and linux, so please forgive me for my trivial 
I have installed MMTK-2.4.1, Numeric-23.1, ScientificPython2.4.5, 
netcdf-3.5.1 (all from source) in Redhat linux 9.0 which has python 
2.2.  The installation of all the programs went throught without 
errors.  However, when I tried modes.py from the normal mode example, 
the calculation halted due to segmentation fault.  Then I looked 
through each module, finding that the trajectory module did not seem 
to work.  When I ran the trajectory_average.py from the trajectory 
examples, I obtained the following the error message: 
Traceback (most recent call last): 
  File "trajectory_average.py", line 16, in ? 
    trajectory = Trajectory(None, 'bala1.nc') 
  File "/usr/lib/python2.2/site-packages/MMTK/Trajectory.py", line 98, 
in __init__ 
  File "/usr/lib/python2.2/site-packages/MMTK/Trajectory.py", line 19, 
in checkNetCDF 
    raise Utility.MMTKError, \ 
MMTKError: Trajectories are not available because the netCDF module is 
I read from the archive that people encountered such problem before 
with rpm, but since I installed the programs from source, I do not 
know how I can fix this. 
Also, I wonder if it is possible to obtain the normal modes in 
3N-dimensional vectors instead of just in frenquencies?   
Thank you for your time.
