Dear Freesurfers,
I'm pre-processing my DTI data with Tracula and i found the following error while running trac-all -prep -c dmrirc_H_P01:
dtifit -k /home/joana/FIU/H_P01/dmri/dwi.nii.gz -m /home/joana/FIU/H_P01/dlabel/diff/aparc+aseg_mask.flt.nii.gz -r /home/joana/FIU/H_P01/dmri/bvecs -b /home/joana/FIU/H_P01/dmri/bvals -o /home/joana/FIU/H_P01/dmri/dtifit *Error: bvecs and bvals don't have the same number of entries* Linux ub029113 2.6.18-164.11.1.el5 #1 SMP Wed Jan 6 13:26:04 EST 2010 x86_64 x86_64 x86_64 GNU/Linux
trac-preproc exited with ERRORS
Although i saw a previous email reporting the same problem i wasn't able to solve it following that email's instructions...
I think there is something wrong with my bvec file since dmri/bvecs.txt only contains zeros.
I've tried changing bvec.txt columns to three decimals and then to 1, -1 and 0 but nothing seems to work.
I've attached my bvals and bvecs files.
Does anyone have any idea why this is happening?
Many thanks to you all!
Joana
