Hi,
I am testing a VBM protocol in which we strip the MR image (using BET) prior
to SPM2 segmentation and normalization. It seems that if the image is
stripped prior to segmentation that the extraction step is superfluous. Two
questions:
1) Is there a reason I am not aware of that would justify the extraction
step after segmentation in such a scenario?
2) If the extraction step is not necessary, then is there a way to turn off
the extraction function? I am particularily suspect of the
defaults.segment.write.cleanup variable in spm-defaults. If I set that to 0,
will that do the trick?
Thanks in advance for your guidance.
Veronica
