Re: Can't match target

[Jonathan Callahan <callahan@xxxxxxxxxxxxx>]

Mike,

There is an exception to the rule

  "The xml variable tags must correspond to the netcdf variable names."

You could have had your grtemp variable defined like this:

  <grtemp name="Temperature" units="Degrees C"
url=="file:/hosts/tornado/vol/vol0/MUSEdata/Ships/NewHorizon/Towfish/232/tow081900all.Avgxyz.nc#griddedtemp">
   <link
match="/lasdata/grids/tow081900all_Avgxyz_nc_XAX1_YAX1_ZAX1_grid" /> 
  </grtemp>


Whenever a url property is defined inside a variable, this overrides the
url property associated with the dataset.  The variable "grtemp" above
uses the url property to associate itself with your dataset and a
particular variable name: "griddedtemp".  The syntax is

  url="file:data_file#actual_var_name" 


There's some more discussion of this in the FAQ on merged datasets.
