Hi Dear Bruce
My problem is bilateral high signal grey matter in T1 image. For example,
in uploaded subject at coordinate of TkReg RAS -59.00 3.00 5.00, white matter
surface is too far out even though I have erased extra white matter voxel in
wm.mgz and rerun. Another problem is grey matter
Hello FreeSurfer Developers,
I'm attempting to create partial volume (pve) corrected images for some of
the subcortical segmentations. I have searched the list and found
discussions regarding how the volumes for pve corrected data can be
obtained by default with the asegstats2table command, or whe
Hi Tamara
you should look at the papers cited in the Neuron paper (the Caviness and
Kenndy ones). They detail the manual labeling protocol that we inherit.

Hi,
I remember looking into this — all the time points for a given subject need to
be specified in the same configuration file, otherwise you don’t get the
longitudinal aspect of the processing.

Hello,
I am wondering where I find the protocol used to segment the ventricles for
Freesurfer version 5.1. Looking at the citations in Fischl et al 2002, I
have found some information regarding the segmentation of the surfaces and
some subcortical areas but not the ventricles. I was hoping to comp
Hi Freesurfer users
I wonder wether it makes a difference when using longitudinal TRACULA if all
timepoints are run within one process (1 configuration file including all three
timepoints) or if it is possible to split it into several independent processes
(with several different configuration

Dear Freesurfer users
I am trying to examine differences between 3 groups in surface thickness and
volume over three time periods (pre-intervention, post-intervention, and
6-month followup). Previously, when only the first 2 time points were
available, I followed the instructions for paired anal
Hello Freesurfer team,
I am having difficulty opening the fsdir folder on freesurfer linux version
(linux-centos_x86_64-stable-pub-v5.3.0). First, I preprocessed it using the
command "recon-all -all -i s fsdir" to get the fsdir folder and it finished
without errors. However, when I tried loading th
