[Freesurfer] BA Labels

Dear FS experts, I have SUV maps for subjects within two groups. I moved these SUV maps into surface then I concatenated the images in the order of two groups then I used the compiled file in a glm analysis to check the difference between the two groups.

I aim to use V1 Atlas to derive the SUV values from the BA labels. I am not sure how to utilize these labels in such analysis. In this context I have two questions:

1. Can these label be converted to ROIs similar to the ROIs derived from wmpar.mgz using the command mri_binarize?

2. in WIKI it was mentioned that the command "recon-all -s subjid -label_v1" output the stat values for every BA label. How can I derive similar stats from the SUV maps in the compiled file.

Thanks in advance John
