[MINC-users] registering the 'old' way

[Sylvain MILOT]

I shouldn't have made this data *public* ... look here instead for an example:

register /usr/local/mni/models/norm_avg_305_mri.mnc \
         /data/analysis1/sylvain/register/mri/anonymous_test_mri.mnc \
         /data/analysis1/sylvain/register/anonymous_test_mrital.tag
