Hi Bruce,
In regard to ?h.curv. i extrated the meancurv from aparcstats2table

to try ?h.curv instead.

Dear FS experts
we constructed a customized template (using make_average_subject) to register

Is there any differe

Hi,
We are currently doing longitudinal FreeSurfer analysis on subjects some of
whom are scanned over a period of 6 years. There were 2 groups. One was the
control group and the other was mTBI group. The hypothesis was the control
group would have a fairly stable cortical and sub-cortical volume (

Hi Doug,
I'd like to use the registration matrix from bbregister to transform
functional data into a cropped FOV that corresponds with the anatomy.
I thought that bbregister outputs a ras2ras transform, so if I could crop
the anatomical volume with a correct header vox2ras, things should be fine.
Dear Freesurfer experts,
I have labels representing clusters that I created using mri_surfcluster on
sig.mgh file using a specific threshold. Now I want to use these labels to
extract average thickness values for every subject. I tried to use
mris_anatomical_stats -l $SUBJECTS_DIR/glm/analyza/clla
selxavg uses scenario #1, which corresponds to the 2nd image below, ie,
all the task regressors are in a single column and not pulled out on a
run-by-run basis. The nuisance regressors are specific to each run.

I'm coming into this a little late, but it seems very complicated. If
understand correctly, you have a volume created in another software
package that you want to map into the freesurfer space. Is that right?
Do you want it in the "native" space of the anatomical or the
"conformed" space?

Dear Antonio,
“-norm3diters“ are the iterations of mri_normalize, whereas “-nuiterations”
refers to the number of cycles of mri_nu_correct.mni. I suppose they both work
in v6. If not you can simply create a file with expert options.
Hope this helps!

Hi,

Could you clarify your original post for me:
By "nothing changed," do you mean that the brainmask.mgz is the same as before
even though you used the new watershed threshold? Or that this changed but
nothing downstream (like the aseg.mgz) changed?

Yes; sorry. The mask is created by an applied docker image which produced

I do not have a transform file I can use so I was wondering if I can simply use

ok, but your mri_mask command line has the string "%s" in it, which is
not correct. You need to specify an actual file name. I also think you
are better off using mri_convert -at to map
the mask into the right coordinate system so that you can then view it in
freeview to make sure it is c

Hi Idil
how did you create the mask and the transform? Also, you can't specify "%s"
on the command line - you need an actual name of a transform file.
