Brainana Viewer

Brainana Viewer is a free, open-source desktop application for exploring the outputs of the Brainana pipeline. Built on NiiVue and WebGL2, it runs on macOS, Windows, and Linux, and lets you inspect anatomical volumes, 3D cortical surfaces, brain atlases, and functional maps for each processed subject (sub-*) in a single integrated interface.

Features

  • Volumes and surfaces — volume slicing and rotatable 3D cortical surface rendering.

  • Surface morphometry — curvature, sulcal depth, and thickness maps on the surface.

  • Atlas overlays — automatic brain-atlas overlays with region identification.

  • Functional maps — display functional results such as retinotopy and somatotopy.

  • Local or remote data — open outputs on your machine or over SSH/SFTP.

  • Multi-subject comparison — view and compare several subjects side by side.

The Viewer consumes Brainana derivatives directly — preprocessed anatomical data, FreeSurfer-derived surfaces, atlas parcellations, and functional maps — so no manual conversion is required.
