Hi mrtrix experts and users,

could you provide me some details about ACT in practice?
is the current version method different from what is described in the
article?

Partial volume (pv) seems to give better results than converted freesurfer
aparc binary maps but tckgen says:* resampling ACT 5TT image to fixel image
space*
is that only to create the seeding mask used for dynamic seeding? in this
case is that just downsampling white matter pv to the scan resolution and
thresholding at .5? or to the tracking step resolution? or else?
Is this resampling also performed for the partial volume values or does it
interpolates dynamically from native provided 5TT?
What is the best 5TT image to provide the software, is the highest
resolution achievable useless?

Many thanks.

Cheers
