Hi THREDDS Folks,

After much fine-tooth combing, I'm still not having any luck adding a new dataset to our TDS for the NCOM global ocean model. My catalotInit.log does not indicate any problems for this catalog either. The only thing that I can think of that differs compared to my existing FMRC collections is that this dataset uses longitudes of 0 to 360 rather than -180 to 180: is that a problem or not allowed? I wouldn't have guessed so. When attempting to access the catalog page for this FMRC (click on "NCOM Global Ocean Model" at http://oos.soest.hawaii.edu/thredds/idd/ocn_mod.html), the only thing I can find in threddsServlet.log is the following:

I have placed logs, my catalog file, and an example NetCDF data file (zipped) in the following anonymous ftp directory:

ftp ftp.soest.hawaii.edu <http://ftp.soest.hawaii.edu>
user: anonymous
pass: <your e-mail address>
cd jmaurer/thredds/

Thanks in advance for your help!,

Hi John:

The problem is that

"../**/ncom_global_sfc_#yyyyMMddHH#\.nc$"

should be:

"../**/ncom_glb_sfc_#yyyyMMddHH#\.nc$"

a messsage:

"Fmrc collection is empty =fmrc:NCOM Global Ocean Model"
