I am looking to use the manual parameterization of dwi2response function.
dwi2response manual input in_voxels output -dirs …
Is there any MRTRIX Function that provides the (X Y Z 3) directions of the
needed voxels by the tensor for the -dirs input?
More specifically, in my understanding it is right to use in this case:
tensor2metric tensor.mif -vector dirs.mif for calculation of the principal eigen-
vector, hence, the main directionality. Or this is not what is required as input?
Thanks a lot!
