Purpose

The module DynaCurve extracts dynamic time curves from the input image.

Usage

The DynaCurve module reads voxel values from its input image at specified positions for all time points available and computes ml.CurveData objects from these values. The curves are available as a ml.CurveList object at the outCurveList field, which can be connected, e.g., to a SoDiagram2D module.

Details

The positions from which the voxel values are read can be specified by a list of point markers or by a list of contours or ROIs.

The output curves are generated in the order found in the point or ROI list. If both point and ROI curves are generated, the point curves appear first in the output curve list.
