Hello,
I have questions regarding the along-tract stats using mri_glmfit and
mri_glmfit-sim with permutation for version 7.2.
1) I ran it and I found a significant result (see attached summary file)
where I expected/found a negative association between FA and clinical
score. how do I know the entire length of the tract and how much was
affected based on the summary file; should I be interpreting the results
from the summary file differently?
2) Also when performing clusterwise correction for multiple comparison for
along-tract analyses, should the bonferroni flag (--2spaces) be included?
This is because it wasn't mentioned/included in the tracula statistics
tutorial nor the publication "Using diffusion MRI data acquired with
ultra-high gradient strength to improve tractography in routine-quality data
".
3) Lastly, is it appropriate to embed the perm.th13.neg.sig.cluster.mgh from
mri_glmfit-sim in dmri_trk2trk?
Many thanks,
Paul
