Hi there - I think I know what it is, but it's a problem that should be
solved if you have the last tracula update. It means that your LANG
environment variable needs to be set to en_US.UTF-8, which the update does
for you.

Hi Anastasia,
I have attached the dmri/bvals and dmri/bvec ("bvals"/"bvecs") and the
dmri/dwi_orig.mghdti* files. I don't know if it's a problem but the
generated bvec file has commas instead of full stop (0,832 instead of
0.832). The input file (attached: "bvec_rows") has full stop. Another thing
is that the generated bvals file has an empty space at the end of the row,
which is not there in the input file ("bvals_rows").
thank you!

Hi Lars - At first glance, these files look fine to me. Do the dmri/bvals
and dmri/bvecs files that get generated look fine too?

Hi,
Trying to run trac-all -c dmric_file -prep, I get an error message stating

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).

----------
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:
