[GEMPAK #PXI-851132]: Formatting SN data for SNEDIT/SNPROF

["Unidata GEMPAK Support" <support-gempak@xxxxxxxxxxxxxxxx>]

Hi Marcia,

I was able to create a working GEM file using the text file that you attached.  
I'm not exactly sure why you were unable to do so.

You mentioned that you're creating a GEM file with SNCFIL before running 
SNEDIT.  You may try running SNEDIT alone, since if SNFILE does not already 
exist, a new file will be created - this is what I did to create the GEM file.

Other than that, I'd say it may be an issue with the binary release, but I 
don't know of any previous issues like this with the OS X binary.

I've attached the GEM file I was able to create for you.  Try the above 
simplified method and let me know if the results are any different.

Best,

Michael James
