Hi Susie - If you can label the connection that you want in trackvis consistently in a set of subjects, then yes, it'd be possible to create your own mini atlas. You'd have to map the .trk files with the trackvis streamlines and the aparc+aseg's from all the training subjects to either the MNI or the CVS template. Then there's a trainfile variable that you can set in the configuration file that tells trac-all where to find the training data. If you decide to go through with this, I can try to document it in more detail on the wiki.

Hi Anastasia,     We were viewing the arcuate fasiculus tract created by TRACULA, and noticed that the tract did not reach Broca's area. While there exists literature that now challenges this neuroanatomical convention, I would like to investigate the possibility of creating and inputting on our own training subjects as priors. Do you know if we can try this? Thank you!
