Thanks for the input. I processed a few subjects (T1-mprage, 0.8mm isotropic) using the -hires flag, with no expert file, which generated nice surfaces.

Is an 'expert_file' required ??

Hi Jim,

In the end it’s an empirical question, but my gut feeling is that the T1 with hi-res flag will be best.

Cheers,

Subject: [Freesurfer] using T2 for hippo subfields

 

Hi. We are acquiring sequences on a pediatric cohort that include a T1-mprage (0.8mm isotropic) and a T2-space (1mm isotropic), and I’d like to run the hippocampal subfields module on the subjects using FS 6.0.

 

Is it recommended/useful to run the multispectral segmentation mode with the additional lower resolution T2 sequence?

I read that you really only benefit if the T2 is of similar or better resolution than the T1.

 

If that’s the case, would it be best to just run with the single T1 but with the hi-res flag in the recon-all command?


Thanks.

Jim
