Hi all, I'm having problems working with NcML aggregations and the 2.2.16 version of the Java NetCDF libraries. I would like to aggregate files: NATL_1_28082006.nc NATL_1_29082006.nc NATL_1_30082006.nc ... along the time dimension. I tried an NcML file like this: <netcdf xmlns="http://www.unidata.ucar.edu/namespaces/netcdf/ncml-2.2";> <aggregation dimName="time" type="joinNew"> <variableAgg name="temperature"/> <variableAgg name="salinity"/> <scan location="/path/to/files/" suffix=".nc" dateFormatMark="NATL_1_#ddMMyyyy" /> </aggregation> </netcdf> This gave me a NullPointerException: java.lang.NullPointerException java.util.Calendar.setTime(Calendar.java:1032) java.text.SimpleDateFormat.format(SimpleDateFormat.java:785) java.text.SimpleDateFormat.format(SimpleDateFormat.java:778) java.text.DateFormat.format(DateFormat.java:314) ucar.nc2.units.DateFormatter.toDateTimeStringISO(DateFormatter.java:184) ucar.nc2.ncml.Aggregation.crawlDirectory(Aggregation.java:817) I think I know why this is. There are other files in the same directory of the form "NATL_120_28082006.nc" and I think the aggregator is trying to match these. Can I arrange it so that only files that match the pattern "NATL_1_#ddMMyyyy.nc" are aggregated, and all others are simply ignored? I am reluctant to change the directory structure of my data because other applications may depend on it.
