Hi Andy,
Based on my understanding from GIFTI specification, your .gii are functional files. I'm not sure if mris_convert supports it.
I'm curious how you got the .gii files.
Best,
Yujing

External Email - Use Caution Dear FreeSurfer Developers,
To analyze functional connectivity, I first got Shen 268 surface-based atlas from Neurovault. Now I want to extract average time series data from my subjects based on the atlas but I have no idea how to make annotation.
All I have is .gii left and right hemispheres atlas files. When I tried mris_convert, it says: DA[0] has coordsys with intent NIFTI_INTENT_NONE (should be NIFTI_INTENT_POINTSET).
Could you please give me any tips for making an annot file from surface-based atlas? Thank you in advance.
Kind Regards, Andy (Junghyun) Kim
