[Met_help] NA/-9999 value?

[John Halley Gotway]

Ming,

Since it didn't work for you, I went and tried it myself.  And it does
seem to work for me.  I did the following:

(1) Edit the file METv2.0/lib/vx_math/constants.h, to change the NA string
from "NA" to "-9999".
(2) In the top-level METv2.0 directory, execute a "make clean".
(3) In the top-level METv2.0 directory, execute a "make".
(4) In the scripts directory, re-run the sample scripts:
cd scripts
./test_all.sh
(5) Then in the STAT-Analysis output file
"METv2.0/out/stat_analysis/stat_analysis.out", all of the instances of
"NA" had changed to "-9999".

I'm wondering if you just ran a "make" without first doing a "make clean".
 If that's the case, then the change would not have taken effect.

And are you sure that you're running the STAT-Analysis version that you
rebuilt and not the original version?

Please try this again and let me know if you're still having the same
problem.

John
