How can I get the objective values calculated in an objective evaluation experiment in an output file?

In WEST 2011/2012 it is not possible to get those values into a file, unless one would do some copy/pasting of the grid that is shown in the "Analysis Properties" / "Variables" / "Time series Criteria" tab. Problem with this tab however is that it doesn't show the aggregated quantity objective values, nor the aggregated overall objective value.

In the upcoming WEST 2014, the "Analysis Properties" have been extended with a new "Run" tab, next to the already existing "Variables" and "Data files" tabs. The "Run" tab gives an overview of all computed objective values (including aggregated objective values), and can be exported through a dedicated button to a variety of formats (Excel, HTML, Text).

For any WEST version, it is of course also possible to create a 1-run Scenario Analysis experiment, from which an output file with objective values can be directly obtained.

How should I interpret the property "Number of Time points" for the percentile calculations?

Percentile computations on time series only make sense when time points are equidistant. This is however not necessarily the case, as the integrator may use a variable stepsize. For percentile computations (lower, upper, median), the software will therefore resample the time series on the basis of a time interval provided explicitly by the user, or a number of time points from which the interval can be derived.
