I'm rerunning it with -no-talcheck. It looks to be hanging on finding control points in the Left_Cerebral_White_matter. Can this one step take more than 24 hrs? The "usual" time for a recon-all was @30 hrs for the other brains.
Thanks,
Deane
Quoting Nick Schmansky nicks@nmr.mgh.harvard.edu:
Deane,
the -no-talcheck flag is your best option now, considering that a manual alignment is no better than the automatic.
What is the age range of your subjects? We're implementing an alternate target consisting of young adults scanned at 3T, which works better for that cohort over the adults in the default target we use.

Hello,
I had a Talairach QA check failure, with the error log indicating a Z = -8
which
was below the criterion of z =-6.
I then used tkregister2 to attempt a manual alignment (no surf orig was available). After visual inspection, the subject and Talairach volumes
looked
really closely aligned already. I did some very conservative rotation and movement in the sagital plane, checked other planes, hit "SAVE REG" and
then
executed
recon-all -all -subjid MYFILENAMEHERE
in the subj directory. I then get the same error, with the same z score.
I've
tried several alignments (very little adjustment each time) with the same results.
I notice that when I hit SAVE REG there is a new 4 x 4 numerical matrix
written
to my xterm screen. The values look very very similar to those prior.
Is there a way to interpret these values to assist me in my manual
alignment?
Should I just bag it and use -notal-check? The majority of my patient set
ran
without errors.
Thank you!
