So my issue is the following :

I have 112 mgh files. (They come from the Yeo 17 Network atlas (we split the atlas in smaller regions). I have extracted the coordinates with :

mri_surfcluster (playing with the thmin option)

mri_vol2label 

and then I have used mri_label2annot with my own color lookup table to combine the 112 files into 1 file. (I have played with --noverbose, --maxstatwinner)

When I try to display, I have the feeling that there is some overlapping because what tksufer dispays, is not very relevant and it is spotty. 

I have attached some screenshots 

Thank you very much for your help,
