The output of a category aggregator calculation results sometimes can be challenging:
• A simple aggregator aggregates an array of results into a single value (e.g. average, sum, minimum , etc.) This result can be easily reported as a single value field
• A category aggregator aggregates an array of results into a smaller array (e.g. average per compound, sum per compound, minimum per compound, etc.) A peak result table can be used to report the results, but many rows appear duplicated and contain redundant information
Solution: Generate a result list, instead of a table. See attached schema how a list gets extended by a repeated group around a set of column values.
Note: Do not miss to clear the aggregator at the end. Average values containing more base values than expected are typically caused by a aggregator that was not cleared.
