Hi Carl: the "fileAccess" is from the old AS. there are some examples here for the new way: http://www.unidata.ucar.edu/software/netcdf/ncml/v2.2/Aggregation.html I often write the NcML and test in ToolsUI, before running in a TDS. The TDS tutorial may be useful: http://www.unidata.ucar.edu/projects/THREDDS/tech/tutorial/index.html ToolsUI can be found here: http://www.unidata.ucar.edu/content/software/netcdf-java/v2.2/webstart/index.html Ticket Details =================== Ticket ID: NHI-804360 Department: Support THREDDS Priority: Normal Status: Closed
