Hello, what command can map VTK file to fsaverage5 space? I want its vertex
number to be 10242. If you know, please give me an example.
Looking forward to your reply___

The WM was cropped out by applying a grey-matter mask in SPM, and I am trying
to extract non-zero voxels with mri_segstats.

We don't have a centrum semiovale label in FS. You could try using the
(Left,Right)-UnsegmentedWhiteMatter in the wmparc.mgz

Hello Experts,
I did like to create a mask for basal ganglia, deep grey matter, and
I don't know. I've never seen this type of analysis. I think with and without
would be valid analyses, but they would be answering different questions, so,
as the scientist doing the study, it is more up to you.

Use mri_label2vol to map the segmentation into the fMRI space, then use
mri_segstats using the --avgwf option to get time courses. Run it with --help

No, you'll have to add it as a covariate. Or you can add --etiv when you run
mris_preproc and it will divide the maps by the eTIV

Traditionally, MG analysis is only run on GM. In principle, it is possible to
run it on WM, but we don't offer that as an option.

For starters, you need to have four classes, HC-Male, HC-Female, CMT-Male,
CMT-Female and not use gender as a variable. Try that. I would also normalize
the age and thickness

Dear Freesurfer team,
It is, but it can be either easy or hard. The easy way is to draw it on
gtmseg.mgz and add an entry into gtmseg.ctab. Probably, you should copy the
gtmseg.{mgz,ctab} to a new file and edit that. Otherwise, you can edit, eg,
apas+head.mgz, and pass that to gtmseg with the --head option. At some

One way you can do it is to specify all the GM ROIs with --rescale Id1 Id2 ...
Otherwise, you can run fscalc, eg,

mgx.ctxgm.rescaled.nii.gz

Hi Dr. Greve,
Sorry to bring this back up, but I didn't fully understand how to calculate the
variance in order to get the confidence intervals for each covariate, so I

Are you talking about outliers across subject? Or across region? I would just
take the FS-supplied value instead of averaging the regions.

We certainly cannot guarantee that tkmedit will work as that is a pretty old

You mean that you are getting a different result between the voxel wise
analysis and the ROI-wise analysis? And you created the ROI from the region
that is significant in the voxel-wise analysis? If so, then I think something
is wrong
