New Features

* Mostly complete support for the NIFTI file format -- see for more details on NIFTI.

* More pervasive image objectmap editing (An objectmap is an image in which
each value represents a different structure). This is now available both
in the Surface Editor as before, but also in multi-slice editing modes as
part of the Mosaic Objectmap Editor and Orthogonal Object Map Editor.

* A preview of the BioImage Suite fMRI tools (still in beta format, being
ported over from the internal version which is based on VTK 4.0 and not
easily redistributable).

* A new animation tool for recording animations and saving them as a set of
.jpeg or .tif files for creating movies for presentation.

* Integration with FSL v 4.0. (Previously BioImage Suite required FSL v
3.1). This needs to be downloaded separately -- see -- and be available in your path.

* Integration with the WFU pick atlas -- you need to download this from Install this either in an adjacent directory to
BioImage Suite (e.g. /usr/local or C:\yale) or set the environment
variable WFUATLASDIR to point to the atlas location.

* A Levelset segmentation module with a version of the Chan-Vese algorithm
and local modifications.

* A variety of small and large improvements in the underlying architecture.

This is essentially a public beta release and we would appreciate feedback
and error reports.
