Hi!

I am using a pipeline that was implemented and validated using fs 5.3 , which does the following:

• compute transformation matrix for linear registration of SUV with T1-2mm, with spm
• use tkergister to transform the matrix into .mat, and then invert the matrix
• use flirt to move T1 images into PET space

The last step gives me different results if I enable FS vs 7, and the registration seems to be off. Do you know why this would be the case?

Thank you! Ludovica
