External Email - Use Caution Dear all, Hi
for checking registration i used fsl applyxfm on an Image(1)(Called Image.nii ) with specific Registration Matrice (Which we suppose to receive when we apply registration Methods) and Generate the "fsl_resampled.nii.gz" (Note: Image Orientations were LAS and in one other Experiment with also the same problem PSR) for our case i will attach the "fsl.mat" (Desired Matrix) using, fsl, freesurfer, and ants i got the correct results (let's call them "fslregistered.mat" and "freesurfer.mat" the converted lta to fsl-liked Matrix) Everything is OK till now But the converted lta-like and fsl-like matrix for ANTs (Which are called ants.lta, and ants.mat) using the lines below: - ConvertTransformFile 3 ./ANTS/ants_0GenericAffine.mat ./ANTS/ants.txt - lta_convert --initk ./ANTS/ants.txt --outlta ./ANTS/ants.lta --src ./Image.nii --trg ./fsl_resampled.nii.gz --ltavox2vox - lta_convert --inlta ./ANTS/ants.lta --outfsl ./ANTS/ants.mat --src ./Image.nii --trg ./fsl_resampled.nii.gz As All Results Images (Registered Image of all Methods) are aligned perfectly i think that there might be some issues with lta_convert Best Regards Yazdan Rezaee J *P.S. *" I've checked the one similar mail one this topic and the conclusion on that was about (sform, qform) incompatibility but the affine matrices of S-form and q-form are equivalent in my case."
