Hi, I have a short question about the additional T2 scan as well. If I perform the full recon-all; recon-all -s mySubject -i myT1.nii -T2 myT2.nii -T2pial -all -hippocampal-subfields-T1T2 do I still have to precise myT2scan.nii.gz T2 for using the t2 for the hippocampal subfields as well ? or it

If the T2 is already high-res, and having already the T1, I don’t think that the FLAIR would help much. Cheers, /E Juan Eugenio Iglesias Senior Research Fellow Translational Imaging Group University College London http://www.jeiglesias.com http://cmictig.cs.ucl.ac.uk/ On 5 Sep 2016, at 16:22, V

Sorry, but a 3-channel segmentation is not part of the future FS6. Juan Eugenio Iglesias Senior Research Fellow Translational Imaging Group University College London http://www.jeiglesias.com http://cmictig.cs.ucl.ac.uk/ On 5 Sep 2016, at 15:54, Jovicich, Jorge mailto:jorge.jovic...@unitn.it>>

Dear Jorge, In my case I am using either T1+T2 or T1+FLAIR. I had no intention of using all three at once, but now I am also wondering if this would be an improvement. Cheers, Renata On Mon, Sep 5, 2016 at 4:54 PM, Jovicich, Jorge wrote: > Hi Eugenio, > > just to confirm I understand the curr

Hi Eugenio, just to confirm I understand the currently available options. There are two multispectral strategies (MPRAGE + high res 2D T2, or MPRAGE + 3D FLAIR). It would be great to see if the combo option improves things even further for the subfields (MPRAGE + high res 2D T2 + 3D FLAIR). Is

The same one; just change the input file and the analysis ID - T2: recon-all -s mySubject -hippocampal-subfields-T1T2 myT2scan.nii.gz T2 - FLAIR: recon-all -s mySubject -hippocampal-subfields-T1T2 myFLAIRscan.nii.gz FLAIR Cheers, /Eugenio Juan Eugenio Iglesias Senior Research Fellow

Dear FS experts, I have a question about the "segmentation with an additional scan - multispectral segmentation" on the hippocampal sf segmentation, FS dev. 6.0. For controls on which I had already run recon-all -all, I added the T2 sequence with the following command: recon-all -s \ -hippocam
