I have tried to inspect the tal xfms that were created in the brief time this string was running recon-all -all -s <tpNid> -i path_to_tpN_dcm while viewing orig.mgz in tkmedit. they were talairach.xfm and talairach.auto.xfm, both were empty and the tkmedit window was empty. upon further inspection the log file is complaining about my nifty.

What program are you viewing it in? If you add a line at the end of config.txt that says "echo $dcmlist" (without the quotation marks) and then run "source config.txt" on the command line, does it print out "DKI.nii.gz"?

Log file indicates manual talairach alignment may be necessary. ERROR: talairach_afd: Talairach Transform: transforms/talairach.xfm ***FAILED*** (p=0.0079, pval=0.0000 < threshold=0.0050) Manual Talairach alignment may be necessary Can anyone provide direction. Alternatively, the error indicates talairach alignment can be skipped with -notal-check flag. Is this step completely necessary? jon

Hi Rotem - No problem. Were these scans by any chance acquired with a coronal slice prescription? In the axial views that you sent, the artifact that you're pointing to looks like misalignment between consecutive coronal slices, which could be due to head motion. a.y On Tue, 25 Jun 2013, Rotem Saar wrote: > Dear Anastasia, > > I tried several times to upload these images in a non-compressed way, but > they were too big and my posts were rejected, with no opportunity for any > other upload way. > Is there any other way for me to upload it so that everyone can see it ? > > Attached are the images in a non-compressed fashion.

Pial surface consistently misplaced
by Jonathan Holt 01 Jul '13

01 Jul '13

Hi all, I'm having a bit of trouble with one particular subject for which we brains for 4-5 different time points. The pial surface is consistently misplaced in the same area, see attached main/aux volume images. I'm hesitant to manually replace the white matter myself as I fear it wouldn't be as accurate. Suggestions on other methods to fix this? The problem is always in the LH temporal right around the lateral inferior ventricle and the fusiform and other subcortical structures.

Hi Daria, the only way is to map the individual curvature to the group space (fsaverage_sym) and see if the curvatures seem to align. doug ps. Please post questions to the FreeSurfer list. Thanks!
