Hi Simon,
The SynthMorph version in FreeSurfer 7.4.1 only supports a fixed regularization value of 1. For more adjustable regularization via the `-r` flag (and improved registration overall), I recommend the latest SynthMorph from the Docker Hub. We distribute a script that supports Docker, Podman, Apptainer, or Singularity: https://hub.docker.com/r/freesurfer/synthmorph
Alternatively, you can download a stable dev build of FreeSurfer, which includes the latest SynthMorph: https://surfer.nmr.mgh.harvard.edu/pub/dist/freesurfer/dev/stable/
Best wishes, Malte

External Email - Use Caution Dear all
I tried to use change the regularisation parameter of mri_synthmorph using -s option in Freesurfer 7.4.1 but this option does not seem implemented. Is there a way to reduce the amount of regularisation?
Thanks for your help,
Simon
