How can I get annual sunlight exposure (ASE) by Openstudio?

Hi,I am trying to do a daylight simulation by using openstudio with Radiance measure. I know that I can get sDA in the Daylight_metrics.csv but I wonder whether it is possible to get ASE with openstudio?

Unfortunately, OpenStudio cannot calculate ASE. At the time the Radiance functionality was being (re)written, the process for calculating the direct sun patches was too onerous (time constraints and storage) for us to consider it. This may change in the near future, as Radiance may be getting some internal improvements to streamline this and other daylight simulation processes.
