1) We've found some subtle differences in tau accumulation between two groups. Unfortunately, it does not survive mri_glmfit-sim (voxel threshold 0.001, cwp < 0.05). Still, I would like to extract the structural measures from the uncorrected tau clusters (p<0.001). What is the most convenient approach for this?

Could the following URL (http://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg16268.html

) be a solution? Can mri_label2label work for sig.mgh with multiple clusters?

2) A slightly unrelated question: how can I go about using this particular cluster as a seed for functional or tractography analysis in other softwares (i.e. FSL or MRTRIX) or even within Freesurfer if possible?

Thanks again. Really appreciate your help!

Best Wishes,

Elijah
