Plotting a Skew-T panel plot

Hello,

I am working with the NCL Skew-T routine to plot four COSMO-EU model
profiles for a special point in time at different gridpoints. As
example I took two helpful scripts from the NCL homepage:

http://www.ncl.ucar.edu/Support/talk_archives/2010/att-0270/skewT_60levs_panel.ncl

http://www.ncl.ucar.edu/Applications/Scripts/skewt_5.ncl

After two days full of struggle, I am sure that my script fails at the
first plot command

> skewtfrz_data = skewT_PlotData(wks, skewtfrz_bkgd, p_data(0,:),
> T_data(0,:), Td_data(0,:), z_data(0,:), windspeed, winddir, dataOpts)

Even if I try to just plot one Skew-T diagram by commenting out all
panel options and other plot commands, the script fails at the above
given line.

The output of the script (eps-format) is given in the attachment.
There you can also find the script itself. As you can see, I have
included a print command right after the plot command:

> skewtfrz_data = skewT_PlotData(wks, skewtfrz_bkgd, p_data(0,:),
> T_data(0,:), Td_data(0,:), z_data(0,:), windspeed, winddir, dataOpts)
> print("frz plotted")

but this print command has never been executed. The script is working
for minutes until the process is killed without any error.

I have already checked the input data which comes from COSMO-EU. In my
opinion, it doesn't contain incorrect values but I also attached all
used variables in the file "skew_T_input_data.txt".

Maybe you can find any mistake in my script?

About the technical background: I am working with NCL 6.1.2. When I
type "uname -a" I get

> Linux 3.1.10-1.16-desktop #1 SMP PREEMPT Wed Jun 27 05:21:40 UTC
> 2012 (d016078) x86_64 x86_64 x86_64 GNU/Linux

I would really appreciate any assistance. Please let me know if more
information is needed. Thank you in advance for your help.

Best regards, Katharina.
