[Wrf-users] copygb.exe oddities

[jcrosby]

Good morning,

I've been playing with copygb and am noticing some weird things while 
trying to merge 2 grib files.

Heres what I'm getting:
jcrosby at Alpha:~/WRF/GRIB_2008_24_12$ /home/jcrosby/WRF/copygb.exe -xg 
212 -M nam.t12z.awip21800.35 nam.t12z.awip21800.36 35to36.00

If you notice I'm merging 35 into 36 and it works. But when I merge 36 
into 35 it fails. But when I try at hour 06z I get the opposite:

212 -M nam.t12z.awip21803.36 nam.t12z.awip21803.35 36to35.03

At 6 it works fine if I got from 36 into 35 but fails on 35 to 36.

Also.

A co-worker who's been running this has been getting segfaults with 
-xg218 being used. I tried it and am getting the same thing. I read 
through the copygb doc file and didn't find mention of what the -xg212 / 
-xg218 mean.

If anyone knows or has raninto the 2 above oddities please let me know.
