Hi Everyone,
Back in May I was very excited to learn that there was some movement toward
allowing Freesurfer to utilize the higher than 1mm iso. resolutions of some
of our structural images, which could be fantastic help in subcortical
segmentations. Is this something that is still in the works
Oops i just realized I only sent this to Bruce:
Thanks! It looks like this involves some manual intervention. Matt., I
assume you're not manually making control points on 1000s of subjects (I
imagine this is for the human connectcome project). Is your code public
somewhere?
Cheers,
Michael
Only because I was lazy! You can use surfaces for normalization too. I think
the script I gave Matt probably had that in it

Dear Freesurfers,
Over the last years, MR imaging technology hasimproved such that sub 1-mm
isotropic scans can be obtained with good signal to noise characteristics.
For example, our lab uses 0.7mm isotropic structural MR images. I
understand that the Freesurfer pipeline will up-sample these to
Hi Joshua
yes, we already have upgraded mris_make_surfaces to take higher res data
and refine the surfaces with it. Haven't tried it on the aseg yet, but if
you upload a sample dataset I could see how hard it is.
cheers

Hi Bruce,
Is there a flag for this on recon-all? Or do you need to use
mri_make_surfaces directly?
Best,
Michael
