Hi Freesurfer/Tracula experts,

 

I would like to use my own diffusivity and anisotropy maps (FA, MD, etc) with Tracula as opposed to the maps generated by dtifit during the course of trac-all –prep. I see that there is a –notensor option to stop dtifit from producing metric maps; however I am wondering if there’s any way to get Tracula to recognize alternative metric maps that I supply to it.

 

My main goal is to sub in my own metric maps for the purposes of having Tracula generate tract profiles (pathstats.byvoxel.txt) with metric maps I generated via an alternative fitting method to dtifit. Is there any way to do this?

 

Additionally, is there any way to have Tracula perform these same types of analyses with kurtosis maps or other types of dMRI data?

 

I’ve been working mainly with Tracula 6.0 as I have received an as yet unresolved mri_binarize error with Tracula 7.2. However, I am curious if the above is possible with either or both versions.

 

Thank you!
