Hi Andy,
Thanks for the information.
The error message that you are getting is actually from GIFTI library. I'm
wondering if any other programs using the same library can parse the .gii
correctly.
I downloaded these files from the site:
shen_2mm_268_parcellation.nii.gz
395091.R.func.gii
395091.L.func.gii
Can you confirm these are the same files you downloaded? To debug it a little
more, can you also let me know your mris_convert command line?
Best,
Yujing

Hi Yujing,
I got the surface-based shen 268 atlas GIFTI file from Neurovault: MailScanner
has detected a possible fraud attempt from "secure-web.cisco.com" claiming to
be
https://neurovault.org/images/395091/<https://secure-web.cisco.com/1nc6gfn6VjjKigEYqWc-8kv59k1M4P4KJsOZNG-wzL9VI7sGz6VtoXvG_MRPd7n1hHecU3LLS5w43aE-t57NFuRIBnv_tzk-0nsXBcpiQ77ZmSTbj2GQVhLK-IB4_Wk3xKYdv4HdSgHx7rjDXvJ5LTWRcOvOKQd8ZFcyhsUVfKTxErlLqydo83AQsb0G4bzx8eRxlK3GbQqE6F2unEOJNs4o7BJbGItXJOSNHKjq-WowGK42iSTozlMFE-bZvVOc1K0TgbWsibZ4E3jwKydRbUsfrTEWlJEoxfxzmHetsxCU1oTcmvcqoEWHB8jjIa8VgsfEyyq3lnHupc-JgRD7NfQ/https%3A%2F%2Fneurovault.org%2Fimages%2F395091%2F>.
It is supposed to have specific values within specific regions like any other
atlases.
What I want to do is to convert the GIFTI file (surface-based atlas) to
annotation, so that I can extract mean time series.
I saw some methods to convert volume-based atlas to annotation, but I haven't
found any ways to do it with surface-based atlas. I actually tried volume-based
shen 268 atlas (recon-all MNI152 -> mri_vol2surf -> mri_vol2label with surf
option), but I can't trust the result - I will send another email regarding
this issue. So I want to cross-check with surface-based atlas, which is
supposed to be easier and more accurate since the atlas itself is on the
surface.
Could you let me know how to convert the atlas of GIFTI file to annotation or
how to extract mean time series using a GIFTI atlas file?
Kind Regards,
Andy (Junghyun) Kim

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

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
