I’m trying to incorporate T2 image along with a T1 to generate 5tt. I am using FLIRT / transformconvert / mrtransform to register images. FLIRT -in T1 -ref B0 2 followed by transformconvert and mrtransform (inverse) to get coregistered high resolution T1. Now, I’ve tried to bring my T2 “to condition” by registering it to: 1.initial T1 and 2. T1-coreg (which is a result form step 1). In both cases FLIRT is followed by transformconvert / mrtransform. Results of both visually are very similar. Neither result 1 or 2 gets through giving error: Provided T2 image does not match input T1 image. Please advise!
