Hi MRtrix community,
I am new in the image registration. I need to use the same transformation that is applied in MRtrix between my imported ROI and 5tt_coreg in another programming environment such as Matlab.
Based on MRinfo, the transformation matrix is as follows:
[0.9999, 0.01036, -0.0008068, -74.4; -0.01037, 0.9999,-0.01142,-97.33; 0.0006884, 0.01143, 0.9999,-53.99; 0, 0, 0, 1]
This is not following the format of affine3d due to the following error I receive in Matlab: The final column of an affine transformation matrix must consist of zeroes, except for a one in the last row.
Also I tried rigid3d and is not working.
Could you please let me know how can I find more information about which type of registration is being used as I can’t find this information in the header.
