Greetings Chiaying! My name is Sean, and I put together the README file and the ncml file. First, I would rename the ncml file from umwmout.nml.xml to umwmout.ncml. Then, I would check the following: In the scan tag, check to make sure the dateFormatMark matches how the date is expressed in your file name. For example, the error message you passed along indicates that your files are named like: umwmout_2012-08-26_12:00:00.nc which means the dateFormatMark should be umwmout_#yyyy-MM-dd_HH:mm:ss" The ncml file I sent used a slightly different dateFormatMark. If everything works, then loading the ncml file using "I'm feeling lucky" is all you will need to do (that is, you won't need to do step three as you described in your previous email). Please let me know if it works with these changes. Cheers! Sean > Hi Tom, > > Thanks for the files. I have tried to use umwmout.nml.xml file.
