Re: [Freesurfer] Different DWI protocols

It's possible that the differences between time points are different for each of the acquisition protocols. In that case, by adding a different acquisition protocol, you may be increasing the variability of your effect across subjects, in which case you'd need a bigger effect size to be able to

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, /E -- Juan Eugenio Iglesias ERC Senior Research Fellow Translational Imaging Group University College London http://www.jeiglesias.com http://cmictig.cs.ucl.ac.uk/ From: on b

[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 additio

Thanks, Aura. What exact version of FreeSurfer are you using? I’m assuming it’s a development version, but from when? The results are indeed weird… -- Juan Eugenio Iglesias ERC Senior Research Fellow Translational Imaging Group University College London http://www.jeiglesias.com http://cmictig.

[Freesurfer] Volume are different in asegstats vs matlab

Hi, I have a question about volume info from freesurfer vs matlab. I am looking at, say, the left hippocampus volume from asegstats, which was 3778.2 mm^3. When I try to get the same volume by loading aseg.nii on matlab, however, I get a different number, 3945. For matlab, I used the followi
