Hello all.
I hope someone can help me with this.
I have some old analyze format data that I am working with now in SPM5. There are two time points for each subject and I am registering time2 to time1 before segmentation.
Here is the problem I am having:
When I register the two images the registration looks great. The results image that is saved shows very good registration and the intensity overlap has converged well. However, when I do a check reg aftewards I notice that image 2 has been flipped. I also see this when just displaying image 2.
So my question is, why is SPM5 adding a flip to the image header?
To provide more info:
1)The data is stored in Neuro format (L=L).
2)The default.analyze.flip value has been set to 0. Just as I had done in SPM2 since our analyze data is already stored in L=L format.
3)I coregistered only, I did not reslice the images.
I am hoping someone can help with this issue as now I am not sure if the segmentation results as all the time2's had this flip. I did not catch it originally as the results screen after registration (as I mentioned above) looked correct.
Is there a default setting I am missing perhaps?
Any help you can provide would be invaluable.
Thank you in advance.
Sincerely,
