Hi Pilar,
You can update freesurfer to 7.1 by installing the rpm (on linux), running the
mac installer, or by extracting the tar archive. The rpm and mac installers
will download freesurfer distributions to appropriate version subdirectories,
so they will not overwrite an earlier version. If

Hi,
Here is my log, deid'd, and attached should be a simple txt file for the config
file. Any thoughts on why I'm receiving this error?:
FREESURFER_HOME /Applications/freesurfer
FSFAST_HOME /Applications/freesurfer/fsfast
I found the answer to my question.
Thanks anyway

Thanks for your reply.
So I did these steps to get the values from the spherical ROI that I created
and got the below error:
mri_volsynth --template $SUBJECTS_DIR/fsaverage/mri/brainmask.mgz --pdf sphere
--sphere-center 150 138 116 --radius 5 --o
Try using --pdf sphere --sphere-center 150 138 116 --radius 5
instead of delta

I think if you delete the ?h.pial files then run

Freesurfer will provide mean thickness for the whole-brain.

Thank you Douglas.
So, as far as I understood, the estimates (cortical thickness for
example) are estimated from rh.pial surface (that comes from FLAIR pial
surface). Since the use of FLAIR decreased the quality of pial

It all comes down to the registration. See

The image may have more-or-less neck and that can change the
registration and ICV. The contrast may be different. The scanner may
have had software updates. You might be comparing dewarped vs not dewarped.

I believe tksurfer will be depreciated if not already. But like I said in the
previous email, freeview does support surface-based label drawing.

Thanks so much Douglas.
Many of the lesions are in the white matter, and many span across WM and GM. In
the case where the lesions on not strictly cortical, is this surface mapping
not possible? Or perhaps a representative surface map showing the occurrences
of lesions in any lobe/ROI?

Thanks Ruopeng. Is surface-based or tksurfer coming back? The surface-based
label drawing was much more powerful than drawing slice by slice in volume
space.

As I found information that FLAIR data could improve pial surfaces

Hi Jesse,
Freeview does support surface-based ROI drawing. There is a Path/Custom Fill

I noticed tksurfer disappeared in the new 7.1 version of freesurfer. While it's
still present in older versions of course, it no longer runs on 64-bit only
operating systems (e.g. OSX Catalina). Is tksurfer going to be updated? It

Assuming these are cortical lesions, you can use mri_vol2surf to map
them as overlays onto the surface. Use the --regheader flag since they
are already in the conformed space. You can even specify the target
