For sub-04, can you look at the nu.mgz volume to see if that looks ok?
Can you also see if the talairach registration looks ok? You should be
able to run something like
tkregisterfv --s subject --fstal
It does not have to be perfect, but it is a problem if it is wildly off.

Hello
I'm processing 7T MP2RAGE data (0.65mm isotropic) with FreeSurfer
8.0.0-beta. I have processed 30 subjects successfully but am
encountering two distinct issues for 3 subjects:
*1. Stack smashing errors during topology correction for subjects with
large defects (sub-06, sub-31):*
Copy*** stack smashing detected ***: terminated
Command terminated by signal 6
This occurs in mris_fix_topology when processing defects with many
vertices:
sub-06: Left hemisphere, defect 0 with 22,492 vertices
sub-31: Right hemisphere, defect 2 with 14,313 vertices
sub-06 does not have any obvious brain abnormalities. sub-31 has some
white matter abnormalities at the terminal zones of myelination (deep
posterior white matter).
*2. Normalization failure for another subject (sub-04):*
Copyerror: MRInormFindControlPoints: could not find enough control points
error: MRInormFindControlPoints failed
This subject has some very minor scattered white matter abnormalities
(perivascular spaces).
*My recon-all command:*
export FS_ALLOW_DEEP=1
recon-all -all -subject ${SUBJECT} -sd ${WORK_PATH}/freesurfer8 -hires
-i ${WORK_PATH}/${SUBJECT}_uni_masked.nii.gz -T2
${WORK_PATH}/${SUBJECT}_t2w_registered.nii.gz -T2pial -expert
${EXPERT_FILE} -openmp 20
My EXPERT_FILE contains two lines:
mris_inflate -n 100
mris_fix_topology -threads 1
*Preprocessing*: Data are processed with 3D Gibbs deringing, ANTS
DenoiseImage, bias field correction and brain extraction prior to
freesurfer.
*Approaches tried: *I have tried running without the EXPERT_FILE, and
also tried with additional recon-all flags -3T -gcut -norm1-n 4
-norm2-n 6, without success.
*Previous successful processing: *The same subjects processed
successfully with FreeSurfer 7.4.1.
*System info: *Ubuntu 20.04, 64GB RAM, 20 CPUs. Subjects are running
in serial not in parallel, and no other processes with significant
memory or CPU use are running on the system at the same time.
Any suggestions would be greatly appreciated. I have attached the
recon-all.log files. Let me know if you need any additional information.
Best wishes
