Hi Juke - I apologize for the late response. I was away and I'm still catching up on email.

It looks like it fails while it's loading the atlas data (here the 4th out of 33 atlas subjects). Does this happen in other cases? Are the cases that fail running on a machine with less memory than the cases that don't?

a.y

PS: I'm assuming you mean "reinit=1".

Hi Anastasia,

After an intial tracula pipeline procedure, I found some tracts were not successfully reconstructed. Their aparc+aseg looked fine to me. So I reran the trac-preproc -prior and trac-path with an option, 'init=1' in a dmrirc file.

Now, the analysis's running well on some, but not the other. I've got an error in trac-preproc -prior:

What would cause this and how can I fix this? Thanks for your help in advance.
