Hi Ged - sorry for the delay, been sitting at the top of Scafell
pondering local maxima.
To convert warp2dof would imply approximating a full warp vector
field by the "dof" spline parameterisation, not a simple invertible/
one-to-one conversion - this would be something that Dan Ruckert
would need to do. However, we do intend to release an approximate
warp-field-inversion program in the next release of FSL (assuming
that we can get the dilithium crystals aligned).
Cheers, Steve.
