Hi Suzan,
actually it uses rigid within-subject registration. The transformation files should be in ./mri/transforms (in long and in base).
Best, Martin

Where is the non-linear registration coming from? Our long stream uses affine.

I appreciate it if you help me with a question on your longitudinal processing pipeline. If I use FreeSurfer to generate an unbiased T1 image template from N time points (non-linear registration), then how can I apply the within subject transformation matrix (Jacobian matrix) to that subject's DTI maps. Does FreeSurfer save the transformation matrix from N.Time-Points toward Template image? and if so, in which folder directory it will be saved? Also, given that FS uses vertices, should I first convert that transformation matrix to voxel space (eg. using surf2voxels ?) and then multiply that into different time-points of one's DTI images. Hope my questions are clear and looking forward to hearing from you:-)
