Hi Yujing,

rh.shen.atlas.1.label is just an output name. It can be anything. Is this what you are asking?

So here is how things have been going. 395091.R.func.gii is a surface version of Shen 268 atlas in GIFTI format, so I thought it needed to be converted into .mgh and I tried mris_convert which failed.
Then I directly tried mri_vol2label and it seems to work fine. mri_vol2label still produces the same error message("DA[0] has coordsys with intent NIFTI_INTENT_NONE (should be NIFTI_INTENT_POINTSET)"), but at least mri_vol2label command did not fail.

It would be appreciated if you could confirm mri_vol2label works fine after you reproduce the command line yourself.
Thanks for your efforts.

Kind Regards,
Andy Junghyun Kim

Hi Andy,

 

I would like to reproduce ‘mri_vol2label --c 395091.R.func.gii --id 1 --l rh.shen.atlas.1.label --surf fsaverage rh’.  Would you mind letting me know how you created rh.shen.atlas.1.label?

 

Best,

 

Yujing

Hi Yujing,

 

Yes they are the files I downloaded.

 

I tried:

mris_convert 395091.R.func.gii rh.shen.atlas.mgh

 

and I got:

** DA[0] has coordsys with intent NIFTI_INTENT_NONE (should be NIFTI_INTENT_POINTSET)

mrisreadGIFTIfile; mris is NULL! found when parsing file 395091.R.func.gii

error: mris_convert: could not read surface file 395091.R.func.gii.

 

As far as I know, the surface files are converted from MNI152 space. Please check Q16 MailScanner has detected a possible fraud attempt from "secure-web.cisco.com" claiming to be https://neurovault.org/FAQ.

 

And there is an update. When I tried: mri_vol2label --c 395091.R.func.gii --id 1 --l rh.shen.atlas.1.label --surf fsaverage rh, it seemed to work fine without converting it to freesurfer-friendly file like .mgh.

 

Kind Regards,

Andy (Junghyun) Kim

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/. 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
