+		ANTs extracts information from complex datasets that include imaging
+		(Word Cloud). Paired with ANTsR (answer), ANTs is useful for managing,
+		interpreting and visualizing multidimensional data. ANTs is popularly
+		considered a state-of-the-art medical image registration and segmentation
+		toolkit. ANTsR is an emerging tool supporting standardized multimodality
+		image analysis. ANTs depends on the Insight ToolKit (ITK), a widely used
+		medical image processing library to which ANTs developers contribute.
