This section of the forum is now closed; we are working on a new support model for WDL that we will share here shortly. For Cromwell-specific issues, see the Cromwell docs and post questions on Github.
why scatter is considered subworkflow?
In the latest development version of Cromwell you started displaying scatters as subworkflows. This created a lot of confusion in our team as having extra workflows like "ScatterAt40_16" is not very useful.
I am also developer of cromwell-client and UI ( https://github.com/antonkulaga/cromwell-client ) it is not clear for me how I should display the scatter subworkflows in my UI as I want to differentiate them from normal subworkflows (that were explicetly written that way).
