Yes, they do. There is also a pcc.nii.gz which is the partial correlation coefficient.

Dear Freesurfer experts,

The freesurfer command 'selxavg3-sess' outputs many files in the contrast folder in addition to the three documented on the Wiki (ces, cesvar, sig). Is there more detailed documentation on what each output is and how they're computed? In particular, I was wondering if the t.nii.gz and z.nii.gz maps contain standard t and standard z scores.

Thanks, Jiahe
