Hi,

I reply to the questions one by one:

1.- The commands look correct. However, the interpretation may be slightly different as now you are not calculating the mean, you calculate the weighted mean. See the full explanation [here](https://community.mrtrix.org/t/fa-ad-rd-connectomes/2301/5).

2.- My understanding is the first option, that it is sampled at every “step” of the streamline. I imagine that the usage of ACT + sampling only at the ends will give, for example, very low values in the FA-weighted connectome. But I don’t know for sure the answer.

I hope this helps.

Best regards,

Manuel
