Hi Douglas,

I would like to plot some values (z-scores) of ROI (grey matter) that are
from freesurfer atlas and would like render them on the brain (freesurfer
atlas) using surf ice. Is there .mz3 for the Desikan-Killarny atlas?

Thanks

[Freesurfer] code for estimating volume

Hi Iglesias,

I would like to learn the  two ways for estimating volumes mentioned in
another post, see below. Please send me the codes in Freesurfer to do this.

Thank you,

Dear Ioana,

This is tricky because the volumes are computed from soft segmentations,
which are not the ones you’re editing. In general, editing outputs is a bad
idea; it may be better to simply discard the cases for which quality
control fails.

Having said that: if you want to use corrected cases, you could compute
volumes by simply summing the number of voxels with each label, and
multiplying by the volume of a voxel (which is 1/27=0.03703703703 cubic
mm). But if you do this, then you need to compute the volume this way for
all cases, including the ones you didn’t edit (you don’t want to mix 2 ways
of estimating volumes).

Cheers,

/Eugenio

Hello,

I'm doing a study about hippocampal atrophy and I'm using the Segmentation
of Hippocampal subfields tool. There were some minor errors and I edited
them using Freeview, voxel edit tool.  I would like to generate a new
[lr]h.hippoSfVolumes-T1.v10.txt
file using the edited [lr]h.hippoSfLabels-T1.v10.mgz in order to see the
new results. What command do i have to use? Is there another way to edit
the hippocampal subfields?And how do i see the results?

I'm using Freesurfer v6.0.0. on macOS Mojave.



Thanks,

Ioana

Dear All,

I would like to perform no partial volume correction of PET  using

mri_coreg --s Patient_1 --mov Patient_1_pet_tac_vol_mean.nii.gz --reg

--no-tfe --psf 0 --seg gtmseg.mgz   --o Patient_1_gtmpvc.output.psf6

I would like to know whether these steps suffices for a no partial volume
correction.

[Freesurfer] what is the argument for arguments for symmetric Geometric Transfer Matrix and two-compartment model (Meltzer Method) in the PETsurfer ?

Hi Freesurfer community,

I would like to know the arguments to use for symmetric Geometric Transfer
Matrix and two-compartment model (Meltzer Method) in the petsurfer command
"mri_gtmpvc".

Thank you,

[Freesurfer] how to include Schaefer atlas into freesurfer and compute surface statistics

2020-01-14 Thread Kate Marvel
External Email - Use Caution

Dear Freesurfer team,

I would like to include Schaefer atlas into freesurfer. The Schaefer atlas
can be found in the link below:

https://github.com/ThomasYeoLab/CBIG/tree/master/stable_projects/brain_parcellation/Schaefer2018_LocalGlobal/Parcellations/FreeSurfer5.3

My question is how can I integrate the atlas in the freesurfer so that I
can run recon-all and calculate the statistics using Schaefer
parcellations, just like aparc_DK40 or aparc_a2009s atlases already
pre-installed in freesurfer


Thank you,
