Hi Thomas,

Thanks for your reply.

The fsaverage directory I have for fs v 5.1 does not include the lh and rh Yeo2011_7Networks_N1000.annot files. I only have this in the 5.3 version of fsaverage. Can I still use the 5.3 version annot files or would I need a seperate set processed with version 5.1?

Kind regards,

Hi Bronwyn,

You raise a good point. You can consider creating a cortical mask using aparc+aseg.mgz and use that to mask the networks. 

However, another approach (which might be more accurate) is to take cortical networks in fsaverage space and transform to your subject's surface and then transform into your subject's volume:

# Transform from fsaverage to subject's surface

>> mri_surf2surf --srcsubject fsaverage --trgsubject yoursubject --hemi lh --sval-annot lh.Yeo2011_17Networks_N1000.annot  --tval $SUBJECTS_DIR/yoursubject/label/lh.Yeo_17Network_native.annot

# Transform from subject's surface into your subject's volume (I am not super sure about this. You probably want to double check the output is correct)

>> mri_label2vol --annot lh.Yeo2011_17Networks_N1000.HS_001.annot --o outfile.nii.gz --hemi lh --subject HS_001 --regheader

Hi Mailing List,

I am attempting to apply the Yeo 2011 7-network fucntional parcellations to a set of fs MRIs processed with v5.1.0. Below are listed the first three steps I plan to take and I am seeking advice as to:

A) Whether this approach is valid.
B) Steps to take next.

Steps 1-3:

1. Run MNI152 1mm template through recon-all
recon-all -i FSL_MNI152_FreeSurferConformed_1mm.nii -subjid Yeo2011_MNI152_FS
recon-all -all -subjid Yeo2011_MNI152_FS

2. Warp the Yeo_atlas1mm.nii.gz to freesurfer nonlinear volumetric space
mri_vol2vol --mov Yeo2011_7Networks_MNI152_FreeSurferConformed1mm_LiberalMask.nii --s Yeo2011_MNI152_FS --targ $FREESURFER_HOME/average/mni305.cor.mgz --m3z talairach.m3z --o Yeo2011_atlas_FSI.nii.gz --nearest

3. warp the Yeo_atlas_freesurfer_internal_space.nii.gz to each subject:
mri_vol2vol --mov $SUBJECTS_DIR/subjID/mri/norm.mgz --s subjID --targ Yeo2011_atlas_FSI.nii.gz --m3z talairach.m3z --o Yeo2011_atlas_subjID.nii.gz --nearest --inv-morph

When previously mapping the Choi 2012 straital parcellations, steps 4 and 5 were: 

4. Creating a striatal mask in the native subject's space from freesurfer segmented Caudate (11 & 50), Putamen (12 & 51), and Accumbens (26 & 58):
mri_binarize --i subjID/mri/aparc+aseg.mgz --match 11 --match 12 --match 26 --match 50 --match 51 --match 58 --o striatum_mask.nii.gz

5. Using this mask to mask the choi striatal parcellations
fslmaths Choi2012_atlas_subjID.nii.gz -mas striatum_mask_subjID.nii.gz Yeo_atlas_subjID_mask.nii.gz

Do I need to do a similar thing for the Yeo cortical parcellations and if so what regions should I include in the cortical mask?
