Nick,
upgrading my RAM is definitely on top of my list. As far as the
documentation that I mentioned, I don't think it's something you can
update. I just remembered that I had seen that on the
Dale/Fischl/Sereno 1999 paper (Cortical Surface-Based Analysis I),
which, I know is pretty old, vis-a-vis all the time-consuming changes
that I'm sure have been implemented since then. In any case, I think
the paper reads "The entire procedure, from intensity normalization,
through segmentation, tessellation, and inflation, runs completely
automatically in about 1.5h on current PC architectures ..."

Subject: RE: [Freesurfer] error with mri_ca_register
The mri_ca_register step typically takes about 10 hours to complete.
It
took 9 hours 37 minutes on the 2GHz machine I ran it on yesterday.
Also, 1GB of RAM is pretty low. All of our machines have at least 2GB
(our minimum recommended), most 4GB. This might actually be the
source
of your problem, as our code does not check when it runs out of memory
(very bad, I know). I'll know more when this second run completes.
But
if it is at all possible to upgrade to 2GB or 4GB of RAM, I *highly*
recommend it. I know with certainty that when someone on the mailing
list upgraded from 512MB to 2GB, these sorts of problems disappeared.
Can you point me to the documentation that says the segmentation takes
2-3 hours to complete? I'd like to update that.

thanks Nick,
I tried processing another subject yesterday and again got stuck
somewhere around mri_ca_register, I believe it said (segmentation
error ... sorry I dont' have the details because I'm in windows
world
right now.) In any case, I had another quick question for you:
I am running Freesurfer on ubuntu, which is installed on a separate
HD
on my computer. Some of my specs are 1GB RAM, 3.2GHz dual processor.
In some of the documetation that I've read, a typical pc takes about
2-3 hours for complete segmentation. It's been taking me about 3
times
that (i'm actually yet to fully segment a subject successfuly ). But
is this normal?
thanks again,
Binyam

Subject: RE: [Freesurfer] error with mri_ca_register
Binyam,
I was able to run mri_ca_register successfully with this subject,
but
I
was using a 'development' build (not the one used publicly), and I
was
running on a 64bit system. So this problem is not a blatant bug in
the
code.
I am going to re-run mri_ca_register again, this time using the rh9
stable build (which is what you used) to see if I can get it to
segfault
(the problem that you are encountering).

I've received the files and will have a look at them today.

Hi Nick,
I have just uploaded the 4 mgz files for the subject. I hope
that's
what you were looking for. I checked the skull-strip and
talairach
registration and it looks fine.
thanks,

Subject: Re: [Freesurfer] error with mri_ca_register
Binyam,
The recon-all.log indicates that mri_ca_register hit a
segmentation
fault, which is bad. Can you send me the subject data so that I
can
try
to recreate this segfault in a debugger? You can upload to me
via
the
filedrop:
https://www.nmr.mgh.harvard.edu/facility/filedrop/index.html
In the meantime, also look at the brainmask.mgz file with
tkmedit
and
confirm that it is skull-stripped and that the cerebellum is
attached.
Also check the talairach registration with tkregister2.

hi all,
I just ran autorecon2 on one of our subjects (for the second
time,
after getting a similar error, i.e. ERROR: mri_ca_register
with
non-
zero status. I just rerun recon-all with -autorecon2 without
removing/changing anything produced by the previous
autorecon2).
Is
there any logical place to start to fix the problem or do I
have
to
rerun mri_ca_register as shown below:
mri_ca_register -align -nobigventricles -mask brainmask.mgz -T
transforms/talairach.lta
norm.mgz /usr/local/freesurfer//average/RB_all_2006-02-15.gca
transforms/talairach.m3z
I have attached the recon-all log for reference.
Please advise,
thanks,
