Hi FreeSurfer Experts,
There are a couple of outliers in my data. I had winsorized the variable, but
now I am trying to use robust regression to weight these outliers in my
longitudinal analyses. In Matlab there is a robustfit function. Is there a

Hi All, I regret to inform you that we are recalling 7.0.0 because we
found some small issues with the way that conforming step was being
performed. The conforming step takes your input volume and converts it
to 256x256x256 1mm and converts the type to UCHAR (8 bit). When
converting to UCHAR, i

Thanks for the reply Doug.
I'm looking for the same number of verts as the *subject* - maybe it's
as simple as I should be registering the subjects *to* the FS average

For thickness, you can look at the difference (or percent difference).
You would use freeview (or tksurferfv, which is a frontend for
freeview). When you run mris_preproc, you can specify that you want it

Hi Alex,
That command just downloads the fs_install_mcr script into your freesurfer

It depends on what you are trying to do with the statistic. But at first

I guess you could apply your transform to both the healthy controls and
to your patient, can then create an FSGD file with two classes as before
but no continuous variable. Then just have a contrast that computes the
diff between the patient and the mean of the controls.

The registration registers the meshes, but it does not alter the number of
vertices in them. There is no 1-to-1 correspondence between the vertices of the
