Before revision:  In this paper, we present the design and implementation of FiberStars, a visual analysis tool for tractography data that allows the interactive and scalable visualization of brain fiber clusters in 2D and 3D  . With FiberStars, researchers can analyze and compare multiple subjects in large collections of brain fibers  .
After revision:  In this paper, we present the design and implementation of FiberStars, a visual analysis tool for tractography data that allows the interactive and scalable visualization of brain fiber clusters in 2D and 3D . With FiberStars, researchers can analyze and compare multiple subjects in large collections of brain fibers using different views .
