Hi,
I just started using SPM and have some questions regarding the segmentation of structural images.
I did segmentation of my structural image using default settings and got the results as seen in the attached
file 'structural_segmented'. The top right image is the original structural image. The bottom image is the normalised image
(using seg_sn.mat and the bias corrected image), which of cause is bad due to bad segmentation.
I manually reoriented the structural image using "Display" where I changed the values "right, forward, up,
pitch, roll and yaw". I then used "Reorient images" and chose my structural image. I did the segmentation on the reoriented image
and got results as shown in the attached file 'reoriented_structural_segmented'. The segmented images are still bad.
Why do a get such a bad segmentation and what can I do to get a better segmentation?
Thanks, Tine
