Dear Freesurfer experts

I'm attempting to running TRACULA in a two subjects(one visit per subject and multiple deffusion scans per visit), as described on the TRACULA tutorial (https://secure-web.cisco.com/1YZplCc8ElxyKpvsfXb9OH_SNhToXmmPHixjCRlcZ51VHS1..., https://secure-web.cisco.com/1nYtHW48eZdU7uUKv6TSjlFm9HP9CHGRmfSeoCOA7uunK3k..., and https://secure-web.cisco.com/1i1x3WraESWH3k6zfmnPSieIq0qc66z7vq-nTTa6dKs81Qa...),

but for my subjects I get the following error when I run the trac-all - prep:

cp dwi.nii.gz /media/sf_share\freesurfer\7.3.2/subjects/diffusion_ tutorial/trc/subject1/dmri/data.nii.gz cp: cannot stat 'dwi.nii.gz': No such file or directory.

I checked the "dmri" directory and found that "data.nii.gz" was missing and "dwi.nii.gz " was there.

I've searched the archive list and I found the following two things; the dwi.nii.gz file is the DWI after all corrections have been made and the data.nii.gz file is a symbolic link to the other, so they should be the exact same file. (https://secure-web.cisco.com/1qq_o3GFIoLx7Luv5Fgj2ZN5KBHCJCZzPPrZqzLzT3BdzI8...)

the data.nii.gz file is necessary for the process of "trac-all -bedp", not "trac-all -prep." (https://secure-web.cisco.com/1pjKE3HFIeU-FqIoHgU1xkoI3rom-BBboaeTQQ7MDiNVT78...).

However, no similar errors have been reported. Does anyone have any thoughts on how to trouble-shoot this one? Also, Ive attached the dmrirc. tutorial, trac-all.log, pre-diffusion_tutorial_tree.text, and post- diffusion_tutorial_tree.text in case it's of any use.

Best regards,

Tomohiro Utsumi.
