If it is an LTA (not .dat file), you can use
mri_coreg --mat2par ltafile
There will be 9 values that come out:
1-3: translation in mm
4-6: rotation in deg
7-9: should all be 1s in this case

Hello,

is there a tool to extract the translations and rotations from an affine transform matrix (register.dof6.dat)?

Best Joerg
