You will need to run mri_aparc2aseg. This is how aparc+aseg.mgz is
created (see recon-all.log file for command). Is the V1 a label or an
annotation? If label, then you will need to convert it to an annotation
(mris_label2annot)

Dear Experts,
I want to calculate PET signal within each Brodman map! I will give an
example: If I want to caclulate PET singal for every parcellate and
segment in the brain I do the following:
bbregister --t1 --mov T1_MPRAGE.nii.gz --init-fsl --reg t1.reg.dat
--s SUBJID
mri_vol2vol --mov PET_MAP.nii --reg t1.reg.dat --fstarg --interp
nearest --o PET_MAP.anat.nii
mri_segstats --seg $SUBJECTS_DIR/SUBJID/mri/wmparc.mgz --ctab-default
--i PET_MAP.anat.nii --mask PET_MAP.anat.nii --sum PET_MAP.summary.dat
How can I do the same previous steps ( or something similar) on the
atlas V1. I.e how can I replace the atalas "wmparc" in the command
"mri_segstat" with the atals V1 to get PET signal for every brodman?.
I can't locate the atals V1 as a file like wmparc.mgz or aseg.mgz is
there any method to creat this atlas?
Many thanks for any advice!
John
