Hello all, a bunch of MINC utilities created here at the Mouse Imaging Centre by Matthijs van Eede, John Sled, and myself can now be found here:

They mostly deal with non-linear registration. A quick summary of what is contained in that tarball is here:

minc_displacement: Create a vector volume containing the displacements at each voxel specified by a transform (.xfm file).
label_volumes_from_jacobians: Compute the volume of segmented structures given an atlas and Jacobian determinants.
xfm2tag: Create a tag file from a transform.
lin_from_nlin: Compute the linear part of a non-linear transform.
scale_voxels: Multiply values in a file by the combined scale factor of a linear transform.
smooth_vector: Blur a vector file.
grid_object_manipulator: Pretty pictures of deformation fields add_noise_to_volume: Add normally distributed noise to a volume.
