What are the differences between the FA images estimated by different Reconstruction Workflows?

Hi, thanks for your development work. I am using qsirecon to process my DKI images. I see that the FA image is also calculated by tensor in the dipy_dki workflow. This is slightly different from the FA image in the other workflow, which one should I use?

Thanks

Hi @liubowen and welcome to neurostars!

What other workflow are you comparing to? Depending on your recon spec there could be few differences. FA from DKI accounts for the non-Gaussian diffusion in the kurtosis fit. There could also be a difference in what b-value cutoff is used for calculating the tensor. And of course, there could be minor differences related to different software implementations.

Best,
Steven
