LONI Brain-Mapping & Brain-Tree Help

LONI BrainMapper movie, using FlashPlayer, rendered by Michael Nazarinia

LONI_Viz and LONI_BrainTree_Viewer allow the user to map back and forth between an atlas, a data set and a brain-tree. The data set is, of course, required to be pre-registered in atlas space, and the brain-tree structure should be synchronized with the structures present in the atlas volume. The later is assumed to be a deterministic anatomical atlas, however, we will soon expand this to structural and functional stochastic atlases.
The following three BrainMapping functions are provided (see the figurative description of each below):

1. Map current cursor location (x,y,z) from the visualized atlas/data ---> onto the BrainTree pathway, and identify the anatomical label of the region the voxel (x,y,z) is part of;
2. Map a user-specifiable ROI-name ---> onto the BrainTree structure, as well as, show the first voxel (x,y,z) part of the named ROI region;
3. Map a preselected ROI from the BrainTree ---> onto the user's data set or the atlas.
