Small warning fix, and update of the documentation.
The template files are now explicitely an input of the T1 preprocessing brick.
Got mixed up between the symmetric and asymmetric versions of the template NIAK_TEST_ALL.
Big change in the T1-EPI coregistration: (1) it is now based on a normalized mutual information (rather than mutual info as before); (2) no correction to a zero mean is applied to the volumes anymore (because it's not necessary anymore, before it was to prevent instabilities in the mutual info criterion; (3) the last step of registration has been suppressed. A simplex of 1 mm on a volume that is typically 3 mm isotropic does not make sense.
Changed the call format for the T1_preprocess brick in the fMRI preprocessing pipeline.
Moved the URLs to download the test data to the NIAK config file.
