Hi Fred – Because of your language setting, unix is using commas instead of decimal points and this is messing something up. Try changing your environment with "setenv LANG en_US.UTF-8” .

Best,

Dear TRACULA users,

I'm trying to preprocess a DTI subject in TRACULA which has an already reconed-all error-free T1. I followed the tutorial, but trac-all -prep exited with errors very fast.

Please find attached the log and error files, and the dmrirc. Also bvals and bvecs (were obtained from dcm2nii). The raw dti.nii.gz has 16 volumes, the first being b0 and then 15 directions.

Any ideas on what could be happening would be much appreciated,

Thanks a lot in advance,

Fred-
