Hello to all the MRtrix community!
As we know, one of the common practices for orienting the streamlines of a tractogram from a “moving” to a “fixed” space is to apply a Warp Field (and/or an Affine Transformation).
A common way of deriving the Warp Field is by means of the registration of 3D volumes (usually T1-w or FA Map) for example using ANTs or FSL.
In a previous post a practical and detailed guide was also reported (thanks maxpietsch): Registration: using transformations generated from other packages
I wanted to ask if there is a main source (a paper) of this method / practice i.e. to warp tractograms using transformations derived from the registration of 3D volumes.
Thank you so much,
