Hi Douglas,
I am only getting the main volumes like putamen right and left, amygdala,
right and left...just gross anatomy.

Dear Freesurfer group,
Could you tell me which is the flag I need to use to get all the brain
parcellation when I run recon-all? It seems I am getting the tables with
few volumes and I guess there is something wrong.
Best wishes and Merry Christmas,
Sorry for the delay. Answers below

Hi Angeliki
not sure if anyone answered, and also I'm not sure that I understand. If
the cerebellum is "brown" in the aseg.mgz that is good - it should be. Is
there a problem with the skull stripping that you are trying to fix?

Hello,
I am dealing with a problem on FreeSurfer a couple of days now.

Hi Shazia
did you only have one input image or did you have two to motion correct

think they are different?

Hi,
I was wondering if you happened to know why the origin of the rawavg.mgz
image is slightly different than the origin of my original structural image
that I "recon"ed to obtain processed FreeSurfer data. Am I doing something
wrong or is this expected? Is there an image that FreeSurfer creates t
Hi Catherine
can you clarify? Are you getting them properly segmented in the aseg? Is
this a disease population? There are a bunch of things going on in the
images you sent, although it's hard to be sure from a single slice. It
looks like your bandwidth is low enough that you are getting a lot
Hi Catherine,
If it's the mtl pial surface around the hippocampus then the pial surface
is not expected to be accurate in that region. See FAQ question at link

Hi Catherine
what version are you running? We have a fix in 5.2 that helps this

Hi,
I am currently editing some scans (ie adding control points etc),
however I keep finding that after the editing often the brains look
"worse" than they did before; especially the medial temporal lobe
area. I have taken care not to put too many control points in/made
sure not to place t
Hi Doug,
Sorry for all the confusion, I misunderstood what we were looking for.
Right now what we want is the volume measurement in each of the
subcortical regions for each subject, which you suggested with the
asegstats2table command.
Thanks so much for your help!
Alex

> Hi Alex, what do you
Hi Alex, what do you mean by a thickness map of the subcortical region?
The subcortical structure are usually characterized by simple volume
measurements (eg, hippocampus has a volume of XXX mm3). There are tools
out there to do voxel based morphometry. Is this what you mean?

Hi Doug,
We don't want to do ROIs because we're trying to get a thickness map of
the entire subcortical region of the brain.
Prior to trying this, we ran a within subjects paired analysis that gave
us thickness maps of cortical surface. We ran these commands to look at
the thickness maps in each
Hi Alex, do you want to do it on an ROI basis? If so, you can use
asegstats2table to create a table of your subjects at the two time
points, then import this table into SPSS. Or you can run the table
through mri_glmfit to do the paired-t analysis.

Hi Doug,
Yes, sorry about that! I realized after I'd sent the email to you that I
should've sent the email to the freesurfer list as well.
We were hoping to look at volume in subcortical regions of the brain --
basal ganglia, hippocampus, amygdala, etc. Do know if there are commands
to do the wit
Hi Tony, you can use bbregister to create the registration file. You
might also look at the multi-modal tutorial on our wiki as this goes
over the steps that you will need to get and apply the registration.
For the 2nd question, you can use mris_anatomical_stats.

Hi Katie,
I don't have a lot of experience in that age range but... are you talking
about the wm.mgz or the ?h.white in terms of accuracy? You should use the
latter, as the wm.mgz is just an initial estimate that gets refined. If
it's unmyelinated white matter control points are probably not t
Hello,
I have some basic questions regarding some Freesurfer reconstructions
that I've made on a set of infant brains (12-15month olds). Overall,
the reconstructions have been successful. The exception being that
the gray matter of the anterior temporal lobes are being
underestimated,
