Hi Freesurfer Experts, I was wondering what the best way to apply two registration matrices to the same data set would be, ideally without re-slicing after the first registration? Thanks, Caspar
Multiply the matrices together to create a new registration matrix. Run tkregister2 to make sure the combination actually works, then use the new matrix as you would any other registration

Hi Caspar,
if you have them in lta format, you can use mri_concatenate_lta to concatenate the transformations and then apply the final transform.
I also created a program lta_convert to convert between different formats (but it is only in our dev version, not 5.3, let us know if you need that).
Best, Martin
