You totally got it, I must say that actually have the Mori tract atlas, in

Hi Anastasia,
Thank you the answers.
One more question, if I'd like to use the scalar images created by
other methods, e.g. non-linear fitting, how can I feed this images to
output the stats like the pathstats? I knew the tractstats2table
will do the jobs, but it is binarized and hard-coded.
I would like to calculate an effect size at each vertex for a two group
comparison of thickness in QDEC in which a single nuisance covariate was
used.
Is there a way to do this with the output from QDEC such that the values
are covariate adjusted?
thanks
Hi Ping - Are you asking how you can produced the stats? You could use
fslstats with path.pd.nii.gz as the mask, and redirect the outputs to a
file that looks like pathstats.overall.txt. You could either keep the same
names for the measures or edit the tractstats2table script to change the
This doesn't look right. Are you certain that your gradient table is
correct? Have you looked at the eigenvectors of the tensor fit to make
sure they're in the right orientation?

Sorry for not being clear. I meant how to calculate path length based
on path.pd.nii.gz, and the Center and Weight Average of the scalar
images?
Thanks.

Path length: that's independent of any external scalar images.
Weighted average: you multiply with the actual value in path.pd.nii.gz,
then average.
Center average: you average only over the voxels in path.map.nii.gz.

So how was the path length estimated?
Thanks again.

Sample paths are drawn to estimate path.pd.nii.gz via MCMC. It's the
average of the length of all path samples that are accepted for inclusion
in path.pd.nii.gz.
