Re: [thredds] Subset service fails as Point Data

Hi Kyle:

The dataset

http://staging.asascience.com:8989/thredds/catalog/Cadiz/Currents/catalog.html?dataset=Cadiz/Currents/EGM200_3.nc

as downloaded doesnt get recognized as a grid. did you modify it with ncml?

Still receiving the same error using version 4.0.20.2.  See original

Here is a dataset where the Point subset is working correctly:
http://staging.asascience.com:8989/thredds/catalog/fmrc/GFS/catalog.html
?dataset=fmrc/GFS/GFS_best.ncd

And another which is not working correctly (same error):

Hi Kyle:

I just made a release (4.0.20.2) that i think will fix this. Can you
download and try again? thanks

Hello all,


I have a dataset that works correctly with the grid subset, ncWMS, and



any other NetCDF tool I can come across.  It is failing with the

Is this most likely caused by an incorrect dataset?
