Yes, you can use that one as well. Lilla ________________________________ From: freesurfer-bounces@nmr.mgh.harvard.edu freesurfer-bounces@nmr.mgh.harvard.edu on behalf of A.R.

Hi Lilla,
Thanks a lot for your help!
isolate_labels.csh --vol aseg.mgz --outprefix aseg_labels --L $label
Do I put the labels 7,8,46,47 where it says labels in the code above?
Can I use the ROI files for co-registration into the diffusion space and then tractography?
Thanks!
Regards,
Akila

The labels that you are looking for are: 7,8, 46, 47
You can use the below command
isolate_labels.csh --vol aseg.mgz --outprefix aseg_labels --L $label
in order to get these from the aseg volume.
That will result in 4 ROI files that you can use in your further analysis.

Is your question then how to isolate the cerebellar WM/GM labels from aseg?

Hi Akila,
Have you run recon_all on your structural data?

Hello Experts!
This is the first time I am doing tractography and my aim is to do it specifically for the cerebellum. I saw online that FreeSurfurer can segment the cerebellum, to create the ROI but I’m not entirely sure how to go about this. So far I have done the pre-processing, co-registration onto diffusion space and created FOD. It would be great if you could give me advice and any feedback about the pipeline.
Thanks for your help!
Regards,
Akila
