Dear everyone,
I sent the recent mail to this list. I agree that it is not a coregistration problem (at least not in my case). I also found out that the problem seems to occur in the smoothing step in DARTEL, because if I perform normalization and set the smoothing kernel to 0 0 0 and then perform the standard smoothing in SPM I don’t get the artifacts.
Hope that can help a bit!
