Dear experts,
About the differences between FSL and Freesurfer, I've noticed that the
left-hippocampus volumes measured by Freesurfer are always bigger than the
left-hippocampus volumes measured by FSL. Is there any reason that can
explain that?
According to the literature, the percent volume
Hi Ana
it can depend on your manual tracing protocol. For example: are
fimbria/alveus part of your definition of hippocampus? For us they are.

Hi Octavian
I'm not clear what you are asking. If recon-all completed, then the pial
surface is already registered to fsaverage via the ?h.sphere.reg surface
and you should be able to use mri_surf2surf to transfer the label into a
common space.

The manual protocol was made by doctors.They traced the hippocampus

For automatic segmentation I've used the following command:

if their definition of what is and is not hippocampus differs from the

Hello,
I have a set of archival data (so I was unfortunately not able to specify the

However, now I'm getting the following error:

Any suggestions? Should I run the following from

no worries. Glad it worked out

maybe the fimbria/alveus is different on the left than the right? Not
sure, but if the protocols are different it's very difficult to make any
meaningful comparison

Hello experts,
I am getting skull strip issues with FreeSurfer recon-all runs in every data.
I ran recon-all on my T1-data and noticed that the skullstrip is not so good.
Almost in every subjects there were dura included, so I tried the suggestion
of using the flags -skullstrip and -Clean–bm

getting rid of all the dura without removing any problem is exceedingly
