Hi,
Attached two spm2.ps files with different head movements patterns: slow
drift in the session and abrupt head movement between sessions.
A couple of questions:
1. In general, is movement between sessions preferable than during the
session and it can be better corrected in realignment procedure?
Consequently, 2 mm drift during the session is much more harmfully than
between sessions?
2. As far as I understand, what I see in spm2.ps is what was really
corrected during the realignment. Is the any tool to make visual inspection
to assess whether realignment was good? Something similar to AnalyzeMovie of
SPM99?
Thanks,
John
