Hi,
The paper entitled
“The Effects of FreeSurfer Version, Workstation Type,
and Macintosh Operating System Version on Anatomical
Volume and Cortical Thickness Measurements”,
PLoSONE, Vol 7(6), e38234 (2012)
may be of interest to all of you. It can be found at:
Dear Freesurfers,
I have previously had no trouble using recon-all to process my
structural scans. However, today I encountered the problem below. I
have looked at postings on this mailing list and it seems this issue
is not a freesurfer one. During my last functional analysis of
retinotopy
Dear Doug,
thanks for putting mri_vol2vol on the ftp site, and sorry for bothering
you again with this. I did as suggested, but I still get an error, now
when attempting to run xhemireg. Apparently nu.mgz is missing.
Please find the log attached.
Thank you very much again,
Irene

Can you send your cmd and terminal output?

Dear Doug,
Following up on tkregister (lets see if my logic make sense).
So, if I use --regheader, the actual transformation that will be written to
register.dat will be this one ?
T* = Tk_vox2ras(B) * inv(vox2rasB) * T * vox2rasA * inv(tkvox2rasA)
where T maps X,Y,Z of volume A (in mm) to
Dear Sir,
When I view a brain volume (e.x., orig.mgz) with freeview and tkmedit, RAS
coordinate differs. Why?
Thank you.

Hi,
I have another silly question. When a functional overlay (say, log p-value
map) is loaded to tksurfer, how exactly are the surface vertex values
computed? using simple interpolation of the loaded map? or is it something
more fancier, like looking along the normal of each surface face and
Hi shay
Are you using mri_vol2surf to sample it onto the surface before displaying in
tksurfer? If so, you get to choose how to sample and interpolate?
Cheers
