track plots

Hello,

I would like to plot storm tracks with ncl.
The tracks are stored in NetCDF and the latitude and longitude
variables both have the form

1: lat1 lat2 lat3 missing missing ......
2: lat1 lat2 lat3 lat4 missing missing .....
.
.
.

so that each track is filled with missing values to a certain length.

I tried to modify the traj_1.ncl script for that problem and modified
the beginning like that:

;*************************************************
; traj_1.ncl
;*************************************************
load "/usr/share/ncarg/nclscripts/csm/gsn_code.ncl"
load "/usr/share/ncarg/nclscripts/csm/gsn_csm.ncl"
;**************************************************
begin
;*************************************
; read in data
;************************************

       lat = addfile("$PATH/TRACK_lat_200704.nc","r")
       lon = addfile("$PATH/TRACK_lon_200704.nc","r")
        ntime=105

Then I get the following error:
warning:TextItem:libncarg Error:PLCHHQ - DATASET NOT LOADED CORRECTLY
Segmentation fault

I hope you could help me.

Regards
Christine
