February 2015: Setting IE to state False/True has no effect at inherit 
When an initiating event is set to TRUE or FALSE in the event tree structure, and inherit is applied (SeqBCMethod=2 or 3) then the setting of the initiating event state does not have impact on the quantification. You cannot set the IE to a state during quantification (via BC-sets). This problem hence only relates to a situation where some event tree should be handled specifically during a quantificaiton (for example sensitivity study). 
If the initiating event is set another input alternative, e.g. a basic event, and this basic event is set to the state preferred.
