Hi,
I have collected a T1w MRI scan using two different scanners for the same patient. In one of these scans, the patient has LPA, RPA, and Nasion fiducials which I have labeled using the "Edit Tagset" Plugin. I want to find the coordinates of these fiducials in the other MRI image where the patient does not have markers on their head. Since I have hundreds of patients like this, I want to find an automated way to do this that is as accurate and efficient as possible.
I tried using 3dAllineate to align the fiducial T1 (containing a tagset) with the other T1, hoping that the tagset would also transform during the process. However, I discovered that the tagset disappeared in the transformed dataset. Is there a way to also transform the tagset? I imagine there must be a way to save out the transformation matrix and then apply it to the coordinates of the tagset, but I'm not sure the easiest way to do this. I know that I could manually edit the tagset in the transformed MRI, but this approach would likely require more time.
Let me know if you have any suggestions!
Thanks
