The Corner Cube Environment (CCE) is a symbolic visualization software package written in IDL which facilitates rapid examination and comparison of activated foci in an anatomical context. Activated foci in functional neuroimaging datasets can be displayed using CCE's ability to interpret focus locations in Talairach coordinates and to simultaneously display two functional volumes. The Corner Cube Environment was developed by the International Neuroimaging Consortium based at the University of Minnesota with partial support from NIH grants R01 DA09246 and P20 MH57180.

Requirements

The Corner Cube Environment software package requires IDL version 5.0 and a C compiler. It runs on Unix platforms supporting 8-bit pseudo-color displays, and functions best on displays larger than 1024x768. The software package is available free; we provide source code and a sample volume, but no guarantees.

Results

We have performed a comparative evaluation of the Corner Cube Environment against maximum-intensity projection and "gallery of slices" displays, and the results suggest that CCE has definite advantages over both conventional display techniques (See Rehm et al. "A symbolic environment for visualizing activated foci in functional neuroimaging datasets." Medical Image Analysis 1998; 2(3): 215-226). The Corner Cube Environment has proven to be an effective tool for summarizing the spatial characteristics of activated foci within an easily understood visual context and is especially useful for displaying the similarities and differences in functional neuroimaging datasets.

The Corner Cube Environment was also featured on the cover of NeuroImage presenting neuroimaging results from Sidtis et al. "Are brain functions really additive?" 1999; 9(5):490-496.

Test Drive

Still not sure whether to download the Corner Cube Environment? Two web-based applications have been developed by INC to demonstrate the functionality and effectiveness of the CCE. The Visualization Testbed compares the efficacy of the CCE, gallery-of-slices and SPM-like orthogonal projections for interpreting neuroimaging datasets. Corner Cube On The Web allows a user to test the Corner Cube Environment from an Internet browser.
