diffusion bundles transformation and analysis

Post by tulu »

Dear Brainvisa expert,
I would like to learn more about the diffusion bundle transformation and diffusion bundles analysis. In diffusion bundles transformation, I read the introduction web page and I have simple question. I don't know how to make roi_1 and roi_2 or more. Should I use roi tool and draw multiple roi in one .arg ? I also did not know how to create the selection rules file. Is there any instruction that I can follow step by step ?( for example, draw 2 roi and create selection rules ?)
Besides, is it possible to do the groups statistic in DTI study using Brainvisa ?
thanks replay
sincerely

Yes, you can use the ROI drawing tool to create the regions that are used for tracking and draw several regions in one .arg.

The selection rules file is a text file that can be created with a text editor. Unfortunately, there is no tutorial on tracking.

To date, you have to extract the information given by BrainVISA and do the statistics with your own tools.
