[Met_help] MET v1.1 test case error

[John Halley Gotway]

Steve,

Thanks for the info.

Have you tried running the cwordsh tool (http://www.nco.ncep.noaa.gov/sib/decoders/BUFRLIB/toc/cwordsh/) to "unblock" the file, and then "reblock" it?

For example, the following commands in a C-Shell would do that:

cd METv1.1
foreach file (`ls data/sample_obs/prepbufr/* | cut -d' ' -f9`)
    /path/to/cwordsh unblk ${file} ~/tmp.unblk
    /path/to/cwordsh block ~/tmp.unblk ${file}
end
rm ~/tmp.unblk

Where "/path/to/cwordsh" points to your version of cwordsh.

We're still trying to figure out all of the variants with these PREPBUFR files.  If unblocking and then reblocking the PREPBUFR files doesn't work, then we should include the unblocked files in the 
sample data.

Please let me know how it goes.  And if you have any questions, we can talk this afternoon after the MET presentation.

Thanks,
John Halley-Gotway

I ran through the test suite calling the test_all.sh script. The tests ran sucessfully until it tried to read the sample prepbufr data.  The log from the test is attached.  The error is found in line 400 of the log and says that the BUFR file is not valid.
