Hi Freesurfer expert,
I am looking for just volumetric quantity of *GM,WM,CSF.*
Can u suggest some commands tat i used or explore so that i get volumetric
data.

Hi Matt
if they are outside of the pial surface at the end of recon-all then you
don't have to worry about them.

Dear All,
We have been attempting to run a cross hemisphere analysis using .curv files,

I have outlined the exact steps within our pipeline below. When fitting any glm
to the data (simple osgm shown below), we find that
yep, you'll need a new version of mri_segstats, which you can find by
following the thread that Louis posted

It could be that there is a problem with one or more of your subjects.
First, look at the mask
tksurfer fsaverage_sym lh inflated -overlay mask -fminmax .5 1
the mask should extend over almost all cortex except the medial wall. To
look at each subject, you can run
tksurfer fsaverage_sym lh

Hidoug,
Thanks doug.
For 1st question,I want to reduce the search space of vertex-wise
analysis to a cluster.
Extract the cluster that you want from the ocn to create a mask, eg, to
get cluster2
mri_binarize --i ocn.mgh --match 2 --o cluster2.mgh
Can you send me
rh.38sb_score.dods.glmdir/38sb_score-dods/mc-z.neg.3.sig.ocn.mgh and

Hi Douglas
it really depends what you are using it for. MPRAGE and it's variants
work quite well, but for example if you are planning a longitudinal study
you might want a multi-echo mprage to minimize distortions across
session.

I'm not sure about freeview, but you cannot do it in tksurfer. You can
take your two labels and create an annotation with mris_label2annot (you
get to specify the color)

Doug,
Thanks for your reply! In the annotation, can one of the label be just outlined
and the other filled?
I would really appreciate if you could provide a step-by-step example for this
one… esp. how to create the colorLUT in this case...
Best,
Daniel

No, you'd have to modify the label itself to exclude the center (and
create an outline). I don't have any code to do this. For the other
stuff, look at the help for mris_label2annot --help

Thanks for both of you for the helps! I also find a 3rd solution: convert one
of the labels to mgh and thus use it as overlay and use the other one as label
in freeview.
Doug: Creating an outlined label sounds pretty cool. I wonder whether either
erosion or dilution would do the trick … some
that's a good way to do it. You don't even need to save it as an mgz. You
can just do tools-labels-copy label stats to overlay, then delete the
label and you have an overlay from it (assuming the label-stat field is
not zero)

Hi Krista,
Can you please run:
more ~/.Qdecrc
and copy paste the output for me?
The rm: No match issue in the qcache is not a problem, it's independent from
the issue of listing lGI in the qdec menu. Even with the no match output in the
qcache command, all the files should have been created
Thanks, Bruce! That is neat!!

mri_morphology for the .mgz
for the label you can do it in tksurfer in the tools-label menu or use
mri_label2label (at least I put it in the dev version, not sure if it is
released yet)

That command definitely will not work. When you ran the command I sent,

Ruopeng, is there a way to load a surface-based timecourse in freeview?

Hello everyone
We are interested in measuring the dimensions of the ventral diencephalon
as part of a general metabolic study. We were wondering how accurate
people consider freesurfer to be at measuring this region currently?
