Hi,<br><br>I wanted to transform mri/aseg.mgz (obtained by the command: make_average_subject) to a standard DTI space. I used the following command to get a register.data applied to the DTI data to obtain to a new DTI data in the Freesurfer conformed space.<br>

<br>bbregister --mov mean_FA.nii.gz --dti --s average --init-fsl --reg register.dat<br><br>and then using tkregister2 to adjust the mean_FA to align well with ?h.avg.white. The new register.dat was saved to replace the old one.<br>
<br>I think that if I can inversely apply the register.dat to aseg.mgz, it would work. However, I don&#39;t know how to reversely apply this transformation file. I tried to use --apply_inverse_transform in mri_convert, but it doesn&#39;t work. Any suggestions would be appreciated.<br>
