Hi Janosch - This makes sense. I do want to incorporate support for the
case where volumes are discarded for quality reasons in the next version,
but it's not possible in the current version unfortunately. You'll have to
generate separate config files for each case. Sorry for the hassle!

Hi Anastasia,
in principle, all subjects were scanned with the same b-values (and bvecs for
that matter). But as it is a pediatric sample, some of them don't have all
volumes (67), because scans had to be aborted. We used a sequence that
distributes the directions in a way that the data from aborted scans should
still be processable.
So, what I was trying to do was shorten the bvals (and bvecs) files to the
length of the respective run (e.g., if it only has 54 volumes, the bvals and
bvecs files are shortened to 54 lines) and include them on a per subject
basis...
Thanks,
Janosch
Hi Janosch - Yes, it assumes that all subjects in your study where scanned with
the same b-values. What is your situation?

Hi,
I am trying to process diffusion data with the longitudinal TRACULA stream. I
want to specify different bvecs and bvals files per scan in the dmrirc file.
For bvecs this is possible using
bveclist = ...
I tried to use
bvallist = ...
but apparently this does not seem to work because trac-all complains that no
b-value file has been specified.
Can only one bvalfile be specified for all scans?
Thanks,
Janosch
