When configuring this filter, selecting a semantic type for removal will prompt you with a list of all children of that semantic type so they can also be (de)selected.
Advanced Semantic Types To Exclude Options
Use "Options->Advanced Semantic Types To Exclude Options" to set choose the predicate for concept removal. There are two choices:
Remove CUIs containing at least one selected semantic type - If this option is selected, a concept will be removed if any of its semantic types appear on the exclude list.
Remove CUIs containing only selected semantic types - If this option is selected, a concept will be removed only if all of its semantic types are on the exclude list.
MetamorphoSys Options
The behavior of this filter is affected by the MetamorphoSys Options
Auto Select Related Items - If this check-box is selected, instead of being prompted with
a list of children of the selected semantic type as described above, the (de)selection of child
semantic types will be automatic. For example, selecting "Plant" (A1.1.1) for removal will
automatically select its child "Alga" (A1.1.1.1) for removal. This is for advanced users who
want this behavior always having to confirm.
