Hello
I have a segmentation which made on MNI space, is it possible to do the
inverse transform to the segmentation from MNI space to each subject space?
does the size of the MNI segmentation (218*182*182) should be a problam?
I was traing :
mri_vol2surf MNI_Segmentation.nii --hemi lh
Hi
I am trying to do an mri_cvs_register for two subjects analyzed with FS-5.1.0
on a 64-bit CentOS linux vmware on a 64 bit windows 7 with 16GB memory. I am
running a signle mri_cvs_register and after certain time the process terminates
with out of memory error.
I have done this work a lot of
Hi Mohammadi-Nejad,
Could you include the command that you submitted and the error message and
log file from when the process terminated?

Hi Mike
that's really strange. Are you sure you recreated the pial??? Can you
double check time-stamps and such? And Euler number to make sure that it is
the same for white and pial? If that all looks right, upload the subject
and send me the command line you used for the rerunning and I'll
Dear Freesurfers,
This is a repeat question as either I did not see the response to the
intial query (I apologise in that case!) or it was never answered. I am
planning to do a longitudinal analysis. After I have processed the data
through a longitudinal stream, should I use the LME model? I
Hi FreeSurfer experts,
I happen to have a participant whose brain lesion from stroke
(hemorrhage) distributed over a wide area. Therefore, the recon-all
result is showing a big whole, about half a size of the cortex, on the
anterior part of the left hemisphere corresponding to the lesion site.
Dear Freesurfer community,
I am running into issues with mri_watershed, which I am using the create
the BEM surfaces. In testing different preflooding height threshold
(recommended for accurate skull-stripping), I am running into the issues
that an -h 56 produces results where the cerebellum is
You need to create a registration between your subject and your MNI
space. Try using spmregister or fslregister (but not bbregister). But
there is a bigger problem in that surface-sampling of ROIs in MNI space
tends not to do very well, but I'll leave that up to you to evaluate

Hi Doug,
Thanks for your continued help with this.
I use freeview -v rawavg.mgz -f lh.pial.native
The problem I was mentioning in my first message though, is that the native
pial surface mesh output from mri_surf2surf is only oriented correctly in
freeview, but not in any other mesh viewer
Another note, I just did a little experimenting, and it appears that using
a RAS oriented image for the initial recon-all run (I've been using all LAS
images) will fix the left-right flipping that occurs with mri_surf2surf.
However the mesh is still oriented incorrectly, such that a-p is facing
Hi,
Is anyone aware of any issues that arise from overclocking and using
Freesurfer? I was looking to see how much it would speed up recon-all with
OpenMP using a stable overclock.

It will just run faster so long as things like memtest86 and prime95 don¹t
have errors.
