Is this for PPMI project? We can provide total hippo volumes if needed.

I don't know what is in the NODDI maps. The way mri_glmfit works is that
if any subject has a 0-value at a vertex, then it will mask out that
vertex for all subjects. Is NODDI something that might have a lot of
0-values? It also may be that one subject has all 0s (eg, if the
regitration was rea
Right, you can't use both --fsgd and --iv. You have to use --iv, so make
sure the order is the same as in the fsgd file.

Hi,
Now I have T1 and T2 images (dcm files) and want to calculate the
hippocampal volume. I find it takes ~20h to run recon-all -all and then
~40min to run -hippocampal-subfields-T1. However, I need to calculate the
hippocampal volume for more than 1,0
I don't know anything about fsleyes or fsl command to extract data. In
FS, you can use mri_segstats after resampling the PET to the anatomical
space (mri_vol2vol). Use the PET as the --i and the aseg+aparc as the
--seg. Alternatively, you could use PETsurfer

Dear Rudolph,
Thanks a lot for your reply! Do you know why does it fail on
holes/edges? Does the algorithm require each triangle vertex to have
1-ring neighbours?
Also, do you by chance know how to use the -a parameter correctly? I did
not observe any difference nor in the results nor in runtime

Hi Doug,
Yes that is exactly the concern that we have.

Hi Daniel - It'll be easier to just preprocess the data before passing them to
trac-all. Topup will be incorporated to the preprocessing for the next version
release. Of course you can replace that part of the script yourself if you
prefer - you'll have to also combine the AP and PA outputs etc

Hi Brian, I'm looking at your data. For the most part, it looks like the
surface placement is accurate. I do find a few places where the white
surface "leaks" into the cortex like in the attached picture just to the

not, p

Hello,
After running recon-all, and attempting to run freesurfer (using the command
"checksurfswmflair") the following error message appears for number of studies:

Anyway, this works:

Hi Maria --
If there are holes/edges in the surface `mris_curvature_stats` it will
fail.

Apology if this is a repeat email. I used the wrong email address in my
reply. I was one of the original
authors of `mris_pmake` although it's been (quite) a few years now. I
do remember that at some point the CLI changed, and given the FS

I would segment the T2s, but using the longitudinally processed T1s/subjects.
Unless the T1s are high-res. Then, segment the T1s ;-)

In that case, would you suggest one to use segmentHA_T1_long.sh instead of
segmentHA_T2.sh (cross-sectional) if one has longitudinal data and T2
high-resolution data? Would one be expected to provide superior results?

Dear Daniel,
Such a script doesn’t exist yet (it’s in the to-do list). The reason why it’s
not a straightforward extension of segmentHA_T1.sh is that resampling the
anisotropic T2s to a common space is not a good idea, given the differences in
