Is it possible to do tractography within a range of FA?

1

Hi!

I am trying to run the anatomically constrained tractography and wonder how I can set a range of FA. For example, I would love to run tractography with 0.1<FA<0.5. Is it possible to do this?

Thanks!

You can generate FA image by dwi2tensor+tensor2metric, and then get the mask image for 0.1<FA<0.5. Finally add " -mask {your fa mask image} " after tckgen command.
