Summary of what happened:
Hello, all. I’ve been experiencing difficulties getting SPM12 to properly unwrap and realign participant data across timepoints as part of the SPM12 / CONN processing pipeline. For a subset of participants, the realignment procedure fails miserably, and we can’t figure out why. All participant data is centered with the origin at the AC along the AC-PC line, and all timepoints were coregistered to the baseline (but not resliced). Any thoughts on why SPM12 may be failing unwarp and realign in these circumstances? Work-arounds or solutions would be most appreciated! Thanks, Jeff
Command used (and if a helper script was used, a link to the helper script or the command generated):
No error code generated, as SPM12 doesn't recognize an error, but the mean functional image over time clearly shows non-overlap.
