==Function==
The ''StateTransform'' filter replaces a state values with values of an [[arithmetic expression]].

Typically, the ''StateTransform'' filter is used as a functional equivalent for cursor hit detection in off-line data analysis, using the output of the [[User Reference:ConditionalIntegrator:ConditionalIntegrator]] filter to determine cursor position.

==Parameters==
===StateTransforms===
Any number of transforms, specified in form of an (N x 2) matrix.
Each row corresponds to a transform.
Within a row, the first column gives the name of the state to be transformed, and the second column gives the expression replacing that state's value.
The expression may also involve the value of the state it replaces.

==States==

==Example==
When the cursor hits a target, a typical cursor movement task sets the ''ResultCode'' state to the number of the target that was hit.
For the case of two targets, and when the filter's input is the integrated control signal as output by the [[User Reference:ConditionalIntegrator:ConditionalIntegrator]], the following ''StateTransforms'' matrix achieves this behavior:
{|State|Expression
|ResultCode|(ResultCode>0)*(1+(Signal(0,0)>0))
|}
