Hello freesurfers,
I am running into some sort of memory allocation issue when running
mri_ca_train. I am simply using an intensity volume and a segmentation
volume to create a GCA atlas. I keep getting this segmentation fault: 11,
which is data allocation error. I have tried using all
Ahh, that did the trick. Thanks!

have you tried conforming the inputs (making them all 256^3, 1mm iso and

Hi Freesurfers,
Does anyone know if it is possible to manually set the brain centroid
during the EM Registration step of the recon-all pipeline. I am using a
non-default atlas, and have discovered that many of my difficulties have
resulted from the brain centroid being incorrectly assigned to

previous steps? I did include the -nogcareg flag with the recon-all command.

Hello freesurfers,
I recently attempted to fix the talairach.lta file from a bad recon-all
run for one of my subjects. I originally thought that the second pass of
recon-all would automatically load this talairach file. However, it looks
like the talairach alignment keeps restarting each time
is not an option. Is
there another way to check talairach.lta?

Hello freesurfers,
Does anyone know the physical meaning of the transform matrix and
the quasinewton matrix outputted during EM Registration of auto-recon2?
For some odd reason, both of them are identity matrices (one's along the

Hello all,
I am experiencing an error during the mri_ca_normalize step of
auto-recon-1 using a non-default atlas (for infant brains). Essentially,
norm.mgz and ctrl_pts.mgz are both outputting as blank files
(completely black). However, brainmask.mgz looks completely fine, which
leads me
Not sure if this helps, but you can alter the output orientation using the
flag --out_orientation followed by LIA (for example). Maybe the input
file needs to be in a specific orientation before it can be converted
properly.

I think the best way to diagnose the issue would be to run the subject

Hello freesurfers,
I have an image that is in RAS orientation with the axial primary slice
direction. Is there anyway to change this to LIA orientation with the
coronal primary slice direction? I am assuming mri_convert would work, but
I'm not sure which flags to use.
Thanks in advance.
