1) If I run along-tract stats with mri_glmfit/mri_glmfit-sim and I found a significant result, how do I know the entire length of the tract and how much was affected? Also, is it measured in mm?
2) 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".
Many thanks,
Paul
