Hi there,

I'm struggling to find a way to co-register multiple (tiny) slabs to one another. The solution I have come up with involves deobliquing all the runs, volreg within-runs and then allineate to a common target. I know it is best to only interpolate an EPI dataset once.

1) Most of this, if not all, can be done with align_epi_anat.py. I am currently using it to create transformation matricies, so that I can use "wsinc5" in 3dAllineate for the final image creation. Should I just be using align_epi_anat.py?

2) Is there any way for me to compute each transformation, including deobliquing, and then use cat_matvec to combine them?

Thanks, your registration tools are incredibly powerful and useful.
