Hi,
I have a question if it's possible to derive DARTEL tensor fields. After running spatial registration using DARTEL pipeline, we can derive Jacobian determinant using a “DARTEL Tools” in GUI using “u” vector field images. However I’m at a loss as to how we can go about deriving tensor fields for each voxel instead of just Jacobian as I want to calculate the trace of tensor. I’m not sure how to convert vector field image (“u” file) into tensor field either.
I appreciate if someone can help me with this.
Thanks in advance
Hedok
