The --paired-diff options just take the difference between adjacently
specfied inputs. You then set up your design matrix or FSGD file and
then run mri_glmfit. The --help for mri_glmfit has a lot of info about
the glm analysis. If you just want to test whether the difference is 0,
you can use the --osgm flag (one-sample group mean).

Please give me more detailed explanations of how to run mris_preproc
--paired-diff or (--paired-diff-norm)? and how to setup the GLM after
run this commend? I could not find needed information on the website.
Thank you very much.

Can you use the --paired-diff to mris_preproc?

Hello, group,
Could anybody tell me how to do the pair T test and the repeat
measurement F test? I will really appreciate if you can share the
steps and GLM of the tests. I am using the old freesurfer group analysis.
Thank you, very much,
Xin Wang
