|           **[1]** *optional* count of transcript variants, *int*

Description
-----------

The data represents information for counts of :term:`DNA variants<DNA variant>` (and also of :term:`transcript variants<transcript variant>` and :term:`transcripts<transcript>` in case of :term:`ws-dataset`) associated with a :term:`decision tree point`.
        
If point is not applicable for counting, data is sequence of one or two zero values.

If evaluation of counts is incomplete, data is ``null``.
