Hi Tetiana,
do you mean the bit of skull left over that is misclassified? I wouldn't
worry about it unless it causes the ?h.white/?h.pial surfaces to be
inaccurate. In general we use the surface-based measures to estimate
gray/white morphometry and the aseg for everything else. It is a minor
Dear Freesufer experts,I would like to do the group comparison of white matter volume in various white matter regions base on white matter parcellation. I have no idea about how to do that. Is it the same as cortical thickness comparison in qdec ? could any one give some guide about how to do that
You can use the data in the wmparc.stats file. You can load that as a
spreadsheet into any stats program (eg, SPSS).

Hi Doug and Freesurfers,
Now that I have re-processed some of my data in Stable 5, I would
like to re-open a previous problem I was trying to tackle:
We are using the Sternberg Item Recognition Paradigm in our study,
which involves the memorization and recognition of groups of 1, 3, 5,
what do you mean that you were not able to get the desired result?

Hi Bruce, Nick, Doug and others:
I have Phantom data from around 900 scans collected across 5 sites in the
US. Does FS have a way of processing Phantom data.
Thanks much,

Hi Alan
what kind of phantom? And what would you want to do with it?

Hi Bruce:
This is an ADNI (Alzheimer's Disease Neuroimaging Initiative) Phantom
principally used for structural T1s. The scans have been acquired over 5
sites all over the US on different 3T scanners (Siemens. Philips, GE etc).
Basically we are trying to morphometrically evaluate Phantom data to
Do you mean a phantom with the uniform grid of beads? I don't think that
we had anything that would process that. We mainly just visualized it
before and after gradient unwarping.

The Something-vs-fix of the original paradigm will not relate to the
2-v-fix of the slope test, though they should look something like the
1-v-fix of the slope test. Have you looked at that? The 2-v-fix will
look more like a difference in the loads from the original (eg, 7-1).

Hi,
I'm new to Freesurfer and am trying to process some data for the first
time. I have two questions:
1. I have done some manual editing of the brainmask for skullstripping,
saving the edits using 'Save As' and the default names. This seems to create
a new group of files separate from the
Hi Cheryl,
1) Yes, just use save not save as
2) this information is already generated and can be found in the
aseg.stats in each subject's stats dir. Some of the information is at the
top of that file.

Hi everyone,
A sort of continuation of an old topic: I am able to load data into matlab
(actually, I now plot the patches in Matlab, in order to be able to control the
color myself, works great), but now I want to be able to get the x, y, z
coordinates of the original data back. For example,
