Hi Anastasia:

I fixed that problem - thank you. However, I have another question. i am trying extract trac data but when I set environment, I get an error message:

csh::alanf@cerebro [/autofs/space/dali_003/users/BW_project_DTI/FreeSurfer_5.3_Data/diffusion_recons] : setenv SUBJECTS_DIR $FreeSurfer_Data/diffusion_recons

FreeSurfer_Data: Undefined variable.

How do I solve this?

Thanks again,

Alan

Hi Alan - I'm not sure where the output from the one subject ends the the other starts. For future reference, it's best to attach the entire trac-all.log files instead of copying and pasting parts of them into your message.

I see two error messages here:
1.      "ERROR: must specify as many DWI dicoms as subjects"
This is as it says. Check your configuration file and see if the numbers of entries in subjlist and dcmlist are the same.

2.      "ERROR: reading /autofs/space/dali_003/users/BW_project_DTI/FreeSurfer_5.3_Data/diffusion_recons//118/dmri/dwi_frame.nii.gz"
I'm guessing the problem is in the b-value table. How many entries are there that correspond to low-b images?

a.y

Hi Anastasia:

Thanks to your advice most of the data have been processed using Tracula. Two brains gave me error messages that are
as follows:
