Mike, my process list does not have Xvfb in it. 'gif' returns NODEVC.  How do I 
know if i have any "x-window displays available?"

Have not tried any other programs I am a novice to GEMPAK.

Hi Jacob,

I'd be curious about a couple of things.  A quick test, try "gif|..." instead 
of "gf|..." just to see if that device works. It'll still output a gif but uses 
a slightly different back-end.  I know you're originally asking about TIFFs, 
but just for the sake of troubleshooting.

Do you have any x-window displays available?  I'm using Xvfb to have X11 
displays available in memory.  Which one gets used is determined by Pete's 
export/setenv display command.  For example, my command for that looks like 
"setenv DISPLAY :9" where 9 is the port number of the Xvfb process.  "ps ax | 
grep Xvfb | grep -v grep" will show you if you have any running and what their 
port numbers are.

Do any other gempak programs work, or do they fail in the same way?

-Mike

Thanks for the responses. I tried setting  "/home/jacob/sfc.tiff"  as well as
