Hi Robert, Here is at least one way to this. See the attached NCML that correctly defines the correct "missing_value" attribute which is the root of the problem here. You will have to change the path to the location of your data file in the NCML. Sometimes NCML is not the optimal choice for a variety of reasons so let us know if that works for you (or properly define the missing_value attribute in the original data). Keep us up-to-date on your progress.
