Convenient concatenation of deformation fields (and linear transforms) #821

Open dchristiaens opened 7 years ago

dchristiaens commented 7 years ago

Consider a case where a user registered FA to T1w in subject space, and registered all T1w to a group average template. Said user now wishes to bring all FA images to template space, in a single interpolation.

Of course, this can already be achieved with warpinit and mrtransform. But the required concatenation of deformation fields and/or linear transform matrices can be confusing to some. Could we implement a direct command for concatenating linear and non-linear transforms, perhaps as extension of transformcalc?

I started coding up a transformcompose command a while back however it got stuck on the back burner.

Now that ISMRM is out of the way I'll finish it off soon.
