The mri_synthsr script in the 7..4.1 release from June 2023 offers 3 models - one version 1.0 model and two version 2.0 models (depending upon the arguments).  The default in the absence of any qualifying arguments is the general version 2 model.

- R.

          if args.v1:
            print('Using version 1 model from July 2021')
            path_model = os.path.join(os.environ.get('FREESURFER_HOME'), 'models', 'synthsr_v10_210712.h5')
         elif args.lowfield:
           print('Using model for low-field scans from January 2023 (version 2)')
            path_model = os.path..join(os.environ.get('FREESURFER_HOME'), 'models', 'synthsr_lowfield_v20_230130.h5')
         else:
            print('Using general model from January 2023 (version 2)')
            path_model = os.path.join(os.environ.get('FREESURFER_HOME'), 'models', 'synthsr_v20_230130.h5’)

Hello,
Thank you for your response.

I have an additional question: I am utilizing Synthsr version 2.0. Is this particular version included in The 7.4.1 version of freeusrfer?

Regards

Dear Freesurfer developers,

Previously, I downloaded the freesurfer-linux-centos7_x86_64-dev-20230331-e304091 version and successfully analyzed some data using this version. Now, I find myself in the need to reinstall Freesurfer, but I am unable to locate the source file on your website.

Could you kindly guide me to where I can find the mentioned version? Alternatively, if this specific version is no longer available, please advise me on which version I should download and install to achieve the same results as before.

Thank you very much for your assistance.

Regards
Hengameh
