[gembud] GDTSER and local ascii data

Hello everyone,

I would like to superimpose a climatology on top of GDTSER plots. I have an 
ASCII file having 365 values, one for each day of the year. I can already 
select the values I am interested in, for a 384h time span. Now, I am a little 
bit stuck in finding a solution to plot this on top of GFS ensemble data time 
series. How can I create a single-location GD file? Is it at all possible?

Best regards,
