Hi,
Will it be possible to incorporate the new hippo subfields atlas and stats
generation in the 5.3 recon-all without having to process everything from
scratch with 6.0?
Thank you,
Andreia
Citando Eugenio Iglesias <e.igles...@bcbl.eu>:
Dear Erik / Angela,
the atlas in 5.3 was derived from manual annotations on in vivo images
that relied largely on geometric rules, and led to volume estimates that
did not agree well with histology studies. The new atlas is based on ex
vivo MRI and agrees better with histology. Moreover, it also has the
option to input higher resolution images (in addition to the standard 1
mm T1), which yield a much better fit of the internal structure of the
hippocampus.
That said, IMHO you can still publish papers with the old tool; you just
need to be careful with the interpretation of the results, and discuss
these issues in the submission.
Kind regards,
/Eugenio

Hi FS experts,
Yes, I'm in the same position and have been trying to do it
longitudinally. Does this mean that the outputs are completely
unreliable and unstable? Should it be parked until the release of
version 6?
Thanks

Subject: Re: [Freesurfer] Hippocampal subfields
Hi all, this is really a terrible news!
I am writing a paper using hippocampal subfields (ver 5.3). What is the
problem with segmentation using this tool? Is it reliable at least on
some
of the subfield?
When will Freesurfer 6 be released?
Thank you
Angela
Hi Georg,
we will be releasing with FreeSurfer 6 a new hippocampal subfield module
based on a more accurate atlas built upon ex vivo MRI scans. However, if
what you are interested in is the whole hippocampal volume, the results
from the new module won't be too different.
Cheers,
/Eugenio

Subject: [Freesurfer] Hippocampal subfields
Dear FreeSurfers,
I am just finishing a paper using output from Hippocampal subfields and
recognized that the current version has been deprecated. I am interested
in volumes of the whole hippocampus.
Are these volumes still valid and can you estimate when a new version
will
be available? Can you provide maybe a brief comment on the decision to
deprecate the current version?
Best regards,
Georg
