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

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
