Re: [Freesurfer] converting preprecessed functional surface data to gifti

2024-01-30 Thread Huang, Yujing
The output looks correct to me. The functional gifti file doesn't have the vertex coordinate information. It is like a surface overlay. It only contains one value for each vertex. The pial and white surface gifti files have the vertex coordinates and information about how triangles are formed.

[Freesurfer] Choice of ICV estimation

2024-01-30 Thread Jackson Lee
External Email - Use Caution Hi there, My question is related to FreeSurfer’s calculations for intracranial volume (ICV): Given the importance to consider ICV as a potential covariate when assessing volumetric differences in ROIs between groups, which ICV output is recommended?

I’m not taking sides on this one, but I’ll nevertheless pinpoint that you can also get a sbTIV using SynthSeg, hehe. Looking forward to reading people’s opinions on this one! -- Juan Eugenio Iglesias http://www.jeiglesias.com From: freesurfer-boun...@nmr.mgh.harvard.edu on behalf of Jackson Le

External Email - Use Caution Based on my personal experience, if you have T1 and T2 MRIs, use the sbTIV from samseg, and if you only have T1 MRI, use the TIV value from CAT12. Next, use the sbTIV from T1 samseg. I recommend not using the eTIV value for degenerative diseases. Woo-S
