How to represent missing values?
How should missing data points be represented? For example, some strain gauges saturate near the end of the experiment and the data is useless. Doing data analysis in Matlab, these values are represented as NaN (Not a Number) as this skips the value when plotting. Is NaN a valid value for archiving the data on the project warehouse (including for successful use of the data for inDEED) or should the value be left blank? Zero is not a reasonable option as it is a value that means something.
