Hi! I am EXTREMELY new to imaging analysis, and I've been tasked with coregistering T1 images with PET scans. I've followed the instructions in the manual and fiddled with the parameters (ie degree of splines, objective functions, etc) but my output is very strange- very small, and zooming doesn't do much to fix the odd orientations ... it's unlike what I've seen in tutorials. No luck viewing the rABC.nii in ITK-SNAP either (but the original T1 & PET can be viewed perfectly fine...). I'm attaching a screenshot, and any guidance as to what I'm doing wrong is greatly appreciated! Thank you so much!
Attached image is a result of:
Co-register (estimate & reslice) --> batch editor reference image = T1, source image = PET, objective function = normalized mutual information, Interpolation = 7th Degree B Spine
