Hi Helen,

I managed to run mri_synthseg on my M2 Mac by coping over the model file to the 7.3.2 version of freesurfer, and installing the tensorflow workaround previously posted on the forum for apple silicon machines.

I have not been able to get it to work on the 7.4 or most recent dev versions unfortunately. The work around for 7.3.2 isn?t ideal, but does the trick.

Freesurfer gurus may have more insight though! Annabel

? Hi R,

Thanks for your quick response.

We actually did that initially and it did not work unfortunately.

Could you provide me with segmentations for a certain scan? Or do you see any other possibility to make it work?

Best,

Helen

External Email - Use Caution

The mri_synthseg script and python in the freesurfer disrtibution you are running are not entirely compatible with the arm64 M1, M2, M3 processors in silicon Macs. You could try installing and running the development build of Freesurfer for the silicon Mac via the link below. (After download, right click on the .pkg installer, and select open with default, then follow the prompts).

https://surfer.nmr.mgh.harvard.edu/pub/dist/freesurfer/dev/freesurfer-macOS-...

We would be interested to know if you run into such issues with the above development build. Please keep in mind a development build can be unstable and has not been tested like an actual release. Your numerical result may differ with the development build compared to the previous build/release.

Dear Support Team,

I'm reaching out for assistance with setting up NextBrain - mri_synthseg.

Unfortunately, I could not make it work. There seems to be an issue with the np.float128-section. This error keeps showing up: <image.png> I have also tried to delete np.float128 from the script (as per suggestion from my colleague). However, the same error showed up.

I'm working on a macOS M1.

I would be very grateful for your assistance.

Best,

Helen ______________________ Helen Friedrich, B.Sc.
