Dear Freesurfer experts,
I am attaching a document showing the segmentation of a brain in version
5.1 and 5.3 with and without a 3-T flag. Image is from a 3-T camera.
What I am wondering about is that it seems that the cortex is too thin in
the later version of Freesurfer (both when using 3T
thanks Anastasia for taking the time
into this, once again!

Hi Anastasia,
You were right ! I fixed ncpts = 5 for all 18 tracts and th preprocessing
step runs.
Thanks,

Hi Matthieu - In 5.1 the number of control points (ncpts) was only one
number, the same for all 18 tracts. Not sure
Hi Doug and Bruce,
I have run recon-all -autorecon-pial -s my_subject after editing the pial by
tkmedit. I donot know wether -autorecon-pial option running the process
stages 24-31. So I want to know wether I need run -autorecon3 option as I run
-autorecon-pial not -autorecon2-pial previously.
Hi Freesurfers,
I would like to make sure I am using the funcroi commands correctly for
anatomical and functional ROI analyses (using the aseg to anatomically
constrain), and I have some questions about the commands.
If I want to extract the average percent signal change in the whole left
Dear experts,
To complete my error, I've got moreover another error in

Dear FS experts,
I have the following questions that I am thinking probably got lost in the list
of emails. I would be grateful if you can help me out. Please find the
questions below.
Many thanks,

Hi Emily, there may be a simpler way to get at what you want. You can
use mri_label2vol to create a mask of the label in mni305 2mm space,
something like
mri_label2vol --label yourlabel --temp
$SUBJECTS_DIR/fsaverage/mri.2mm/orig.mgz --regheader
$SUBJECTS_DIR/fsaverage/mri.2mm/orig.mgz --o
Hi Jared
for the ones that run quickly and end, it's because you haven't told it
to do anything. The first couple of lines of the recon-all.log file give
the command line as:

Dear All,
Does anyone know how to run regression (with covariates of interest) in
freesurfer. I know people usually do group comparison but I need to do
regression with a continuous variable. Or do I have to use SPM?
Cheers,

Hi Sean
An
important issue in the LME model concerns the centering of the times
of measurement. It changes the interpretation
of both the mean response and the variance of the random effects.
If tij represents time since baseline then the subject-specific intercept

Hi Bruce,
Thanks for your response. It's a bit of a pain to access the dicoms, but it's
possible. The bigger problem now is that I can't get freeview to work. I type
in freeview into the command line and receive the following error:
freeview.bin: error while loading shared libraries:
Hi Jacky, have you looked at the group analysis tutorial? It includes
instructions on how to include age as a continuous covariate.
