[Camino-users] probabilistic tractography

[Mojdeh Zamyadi]

Thanks for the reply! Based on what I read, it means that I can use the 
whole atlas, right? no need to produce separate seed regions, am I right?

I've transformed the AAL VOIs into the DTI space of each subject using linear and nonlinear registration. My question now is, should I use "track" command with "-inputmodel bayesdirac" option and use the whole transformed AAL atlas as seedfile (eg. -seedfile Control/aal_ROIs/aal_tformed.nii.gz)? Or should I create separate mask/seed images for each region and perform the tractography for each seed? Also, how can I get the the tracks between two seed regions? Your help would be greatly appreciated!
