yes, that's the kind of thing I was worried about. You need a relatively high resolution set of T1s (mprage, FLASH/SPGR, close to 1mm isotropic).

actually I wanted one from tkmedit. Can you tell us something about the acquisition? What kind of scan is it? What resolution? And if you can send us images from tkmedit in coronal and sagittal view that would help too (say of the orig.mgz)

I have two sets of dicoms: one is an axial view, while the other is coronal (this is the one i was using). I attached a screenshot. I'm not sure if that's what you wanted?

Hi Mia
can you clarify what you mean by "a different set of dicoms"? Did you acquire more than 1 T1-weighted structural on this subject? And can you send us an image of the acquisition, say in coronal view?
thanks Bruce

Hey Allison,
Thanks for you help. What do you mean by check your talairach? I'll hold off on using a different set of dicoms, and make that my last resort since it takes a day to complete.

Hi Mia, You may want to check your talairach to make sure that looks okay. If that's not causing the problem, you can edit the wm.mgz to remove the cerebellum and then rerun and this should fix the problem. Allison

It says that it couldn't open rh.orig.nofix and lh.orig.nofix. On the popup image, it doesn't look like the skull is present, but it does look like the cerebellum is. ________________________________________ From: Allison Stevens Player [astevens@nmr.mgh.harvard.edu] Sent: Monday, May 14, 2012 1:28 PM To: Borzello, Mia Cc: freesurfer@nmr.mgh.harvard.edu Subject: RE: [Freesurfer] "cannot allocate memory" issue
You can do: tkmedit subjid filled.mgz rh.orig.nofix -aux-surface lh.orig.nofix
When you downloaded FreeSurfer, you would have also received the subject "bert" who is a good example to compare to. He will likely be located in: $FREESURFER_HOME/subjects/bert
If you do the same command above for bert: tkmedit bert filled.mgz rh.orig.nofix -aux-surface lh.orig.nofix
You'll see what the filled.mgz should look like. Allison

How do I check this? (Apologies for my ignorance.) So I might need to just use a different set of dicoms then?

It looks like there is too huge a topology error for it to continue:
CORRECTING DEFECT 23 (vertices=143258, convex hull=19937) Excessive topologic defect encountered: could not allocate -729782272 edges for retessellation Cannot allocate memory
I would suggested looking at the filled.mgz to make sure skull and/or cerebellum are not included. Allison

Hi all,
I was wondering if you could help me figure out why the recon isn't running to completion. I've attached the log file (recon-all.log), but it's unclear to me what I should do to fix this problem. I tried to compute the lh.pial, but I guess it was never made in the recon.
Thanks so much, Mia
