Hi Colm - Note that the information in the tutorial (particularly the part where gradient tables can be formatted in 3 rows or 3 columns) pertains to the latest tracula update:
http://surfer.nmr.mgh.harvard.edu/fswiki/Tracula#Updates
You're using an older version that only supports the 3-column format. I have no idea if this is what's causing the error without looking at your trac-all.log, but this would be a first guess.

Dear Experts, I am very new to TRACULA, I apologise for what is probably a silly question. I’ve got the following error on running trac-all –prep (FreeSurfer 5.2.0): awk: cmd. line:1: fatal: cannot open file `0' for reading (No such file or directory) mri_concat --i /home/k1193186/FreeSurfer/TRACULA/ROLAND03A/dmri/dwi_frame.nii.gz --mean --o /home/k1193186/ FreeSurfer/TRACULA/ROLAND03A/dmri/lowb.nii.gz niiRead(): error opening file /home/k1193186/ FreeSurfer/TRACULA/ROLAND03A/dmri/dwi_frame.nii.gz ninputs = 1 Checking inputs ERROR: reading /home/k1193186/FreeSurfer/TRACULA/ROLAND03A/dmri/dwi_frame.nii.gz Can anyone tell me what this means and how to fix this, please? I’m guessing I’ve set up my configuration wrong or have the files in the wrong place? Many thanks! Best wishes, Colm. King's College London
