LABORATORY OF NEURO IMAGING 3D VISUALIZATION TOOL

LONI Visualization Tool (LONI_Viz)®

General Description

The Laboratory of Neuro Imaging's 3-D viewer, LONI_Viz, is a versatile tool for volumetric data display and manipulation. LONI_Viz is a completely portable Java-based software, which only requires a Java interpreter and a 64 MB of RAM memory to run on any computer architecture. It allows the user to interactively overlay and browse through several data volumes, zoom in and out in the axial, sagittal and coronal views, and reports the intensities and the stereo-tactic voxel and world coordinates of the data. It also allows the expert users to delineate structures of interest, e.g., sulcal curves, on the 3 cardinal projections of the data. These curves then may be used to reconstruct surfaces representing the topological boundaries of cortical and sub-cortical regions of interest.

LONI computer environment set-up requirements. Please put the following two lines in your ~/.cshrc file
- # LONI VIZ
  set path=($path /usr/lshare/java/LONI_Vis/)
- # JAVA settings
  setenv CLASSPATH .:/usr/lshare/java/LONI_Vis/
- Then Type on the command line
  LONI_Viz_driver
Outside LONI computer environments (require properly installed Java 1.2+, Java 3D and correctly set PATH/CLASSPATH environmental variables)
- (Windows) Click
  LONI_Viz_driver winwods batch executable to start the entire LONI_Viz package
- (Windows) Click
  LONI_Viz_VR_driver winwods batch executable to start only the 3D VolumeRenderer and look at IMG raw data files in 3D
- (Other Environments) Click/Start from the JAR file
  java -jar LONI_Viz.jar [file]
