+The image depicts the hierarchical relationship among GATK-SV 
+Docker images. Arrows indicate the flow from a base image 
+to a derived image. The base image, located at the arrow's 
+starting point, shares its content which is then expanded 
+upon and modified in the derived image. In simple terms, 
+the derived image inherits the same tools and configuration 
+as the base image, while incorporating additional settings and tools.
