My complete datasetScan element that generates the dataset is this:

 <datasetScan name="MET Norway" ID="arcticdata/metno" path="arcticdata/
met.no" location="/metno/damocles/arcticdata/met.no/">
    <metadata inherited="true">
      <serviceName>allServices</serviceName>
    </metadata>
    <filter>
      <!-- hdf and grb files have problems with opendap/wms service
      <include wildcard="*.hdf" />
      <include regExp=".*\.grb(\.gz)?" />
      -->
      <include regExp=".*\.grb(\.gz)?"/>
      <include regExp=".*\.png"/>
      <include regExp=".*\.bufr(\.gz)?"/>
      <include regExp=".*\.nc(\.gz)?"/>
      <exclude wildcard=".*"/>
    </filter>
  </datasetScan>

It has not been changed since we were using TDS 4.3.
