[Freesurfer] mapping from Desikan-Killiany regions to resting state networks

External Email - Use Caution Dear list, I would like to find a reasonably good mapping from Desiken-Killiani ROIs and as many of the resting state networks as makes sense, e.g. salience, visual, etc. I have made a start using the network <> ROI mapping in the Conn Toolbox b

External Email - Use Caution Hi Douglas,  Thank you for your reply. I'm a beginner in freesurfer and my previous statement was not very clear. My purpose is to generate new .mgz files (e.g., scalp.mgz and CSF.mgz, etc.) that are not in the MRI folder.  Bset regards,  Yichuan

everything except skull and scalp are in the aseg.stats file. You can get skull by running samseg, eg, cd subject/mri samseg --i orig.mgz --o samseg there will be a stats file in the samseg folder with skull volume in it On 2/1/2023 5:00 AM, 江一川(JIANG Yichuan) wrote: External Email - U

You can use the --pvr (per-vertex regressor) option in mri_glmfit. But if you are testing for a difference between groups, there is no valid way to do correction for multiple comparisons. Look through the archives as I have explained how to do it several times through the years. On 1/26/2023 6
