Hi,
Trying to run trac-all -c dmric_file -prep, I get an error message stating that there are different numbers of entries in the bval and bvec files. I don't understand why, since both have the same number of rows (64).
OS = Ubuntu 14.04.4 Software: freesurfer-Linux-centos6_x86_64-stable-pub-v5.3.0; I have updated Tracula and FSL (v 5.0.9).
Error message:

---------- I also tried flipping the bvec/bval files, but got the same error. I don't know if there's anything wrong with the bval/bvec files, or if this error message is indicative of some other problem. Is the updated Tracula version only compatible with the dev version of FS?
I have attached the bval/bvec files and the trac-all.log.
------------------------------------------------------------------- The contents of the dmric file is:
setenv SUBJECTS_DIR /media/lmr2/subjects/DTI set dtroot = /media/lmr2/subjects/DTI/tracula_2016_nativerows set subjlist = (4_FS) set dcmroot = /media/lmr2/subjects/DTI set dcmlist = ( 4/5/1.dcm ) set bvalfile = /media/lmr2/subjects/DTI/bvals_rows.csv set bvecfile = /media/lmr2/subjects/DTI/bvec_rows.csv
Thank you!
