It is my understanding that in SPM5 bias correction is applied to all
the images before they get segmented, whether you choose to save the
bias-corrected image or not. Is this correct?
Also I found that with some of my images segmentation results improve if
I take the saved bias corrected images and segment these instead of the
raw images. If I understand this correctly, these images get
bias-corrected twice. Is this OK to do?
