Hi everybody,
I'm trying to run trac all -prep on my data but I'm getting this error
"bvecs and bvals don't have the same number of entries". I've checked my
bvals and bvecs, which are in attach, but they seems to be formatted in the
right way. The other 2 bvals and bvecs in DTI folder are the one
No problem. By original I mean the file that you specify by "set bvecfile
= ..." in your config file. That one need to be in columns, not rows.

Thanks! What do you mean by my "original TLR108.bvec file"? I think the
issue may be that the bvec and bval files were originally created using
dcm2nii before we had decided to use Tracula. I am just having trouble
determining in which directory the original bvec and bval files were
created, becaus
The problem is that your original TLR108.bvec file is still in 3 rows, not
3 columns. You need to transpose the rows into columns.
Yes, there's an example config file that comes with the 5.3 distribution
and it's as usual in $FREESURFER_HOME/bin/dmrirc.example. It's also
described on the wiki,
Thanks. What do these files look like?
/export/data/brain1/RSTOM/TLR108/dmri/bvecs
/export/data/brain1/RSTOM/TLR108/dmri/bvals
These are the ones that the error message in trac-all.log is about, so
something probably goes wrong with the conversion from your original
files.
Also, I recommend ve
Hi Laura - First of all, which version of freesurfer do you have? It looks
to me like you've based your config file on the old example file that came
with version 5.1.
Second, could you please convert your bvecs and bvals files to 3 columns
and 1 column, respectively, then run trac-all and sen
Hi Laura - This means that there is only 1 line in each of the files, so
the end-of-line characters aren't recognized. I'd make sure that the file
is saved as plain text.

Hi Laura - I don't think the error "bvecs and bvals don't have the same
number of entries" should have to do with interspersed zero b-values. When
you run "wc -l" on the bvecs and bvals files, what do you get?

Hi Laura - Were these bval/bvec files created on windows or with excel by
any chance? When you view them in unix (with the more command for example)
you'll see an "^M" character instead of every end-of-line. Can you try
editing these files in a unix editor to fix that? Let me know if this
