[Mrtrix-discussion] ACT: minimum streamline length criterion

[Ulrike Kuhl]

Dear MRTrix team,

I want ot use anatomically constrained tractography as explained in the Smith (2012) paper using the 'tckgen -act ...' command.
However, I'm a little unsure about the minimum streamline length option: if I do not call 'tckgen -act ...' with a specified '-minlength' option, does the algorithm automatically use the white matter fraction path integral criterion as explained in Smith (2012)?

Thank you very much for your help!
All the best and have a happy Christmas!
