1. Is there any way to get a handle on how bad EPI warping is?
2. Is EPI warping dealt with by using EPI-->EPI-template Talairach
normalization (e.g. as compared to coregistration to subject's T1, followed
by T1-->T1-template).
3. Are there any tools in the SPM community for unwarping EPIs? (I mean
after-the-fact; my scans don't have any "field maps" or whatever that would
enable me to use some of the algorithms out there.)
