Tagged: registration errors
Hello,
I have a post-op CT scan chalked full of artifact. As a result, none of the registration options via the GUI resulted in a decent enough registration (post op CT to pre-op T1) to accurately construct electrode placement. However, using a normalized mutual information approach in FSL fixed this poor co-registration.
When I tried to rename the FSL output to incorporate back into the lead DBS normalization pipeline, it error-ed out, stating the registration matrices were misaligned.
Is there a standard way to incorporate outside CT-T1 registrations back into the processing pipeline?
Thank you for your help,
Best,

Hi Kurt,
the rpostop_ct.nii needs to be resliced to the anat_*.nii files for it to work.
You can do so by calling
ea_conformspaceto(‘anat_t1.nii’,’rpostop_ct.nii’)
but please note this changes/overwrites the rpostop_ct, so better make a copy of it.
After that make sure images are still co-registered (e.g. with SPM).
then it should work.
Best, Andy
Great, Thanks Andy.
That worked perfectly!
Best,
Kurt
