Re: [Freesurfer] Cortical thickness

This file is always created by mri_glmfit-sim. It might be named something different depending on your parameters (should always end in y.ocn.dat) doug

Hi Doug,

This file that your saying, will be created after glmfit-sim is done using the cache function and a threshold of 1.3 and absolute ,with y being the fsgd file? Am I understanding this correctly?

Thank you

Joshua

There should be a file called something like cache.th13.abs.y.ocn.dat.
This will have a column for each cluster and a row for each
subject. The
value in the row will be the input for each subject.
