Group ICA Toolbox (GIFT and EEGIFT)
The MIND Research Network
Group ICA Toolbox is a MATLAB toolbox which implements multiple algorithms for independent component analysis of group magneto resonance imaging data (GIFT) and electro encephalogram data (EEGIFT) to group studies.
NIfTI-1 support
GroupICAT v2.0a reads and writes Nifti data.
Vince Calhoun, Tom Eichele, Eric Egolf and Srinivas Rachakonda
GIFT Toolbox is free to download and it is an open source project.

Other information
We now provide EEGIFT toolbox for analyzing group ICA on EEG data (By Tom Eichele). EEGIFT contains options for importing data in .SET format from EEGLAB and visualization methods for viewing group ICA components. Both GIFT and EEGIFT are subsumed within GroupICAT v2.0a.
