[Mrtrix-discussion] Number of tracks

[Luis Morís]

Hello everyone,

I write because I have started to use mrtrix, and I've found a doubt.
To be able to do tractography you have to use the parameter -number
that will set the exact amount of tracks that will be calculated.

My doubt is how does the program decide which tracks to include or
not. If I set it to 1000 and I run it again with 1000000. What
difference do I find between the two set of tracks? Is it purely
random, depends on the length, the FA...

Thanks a lot in advance,

Luis.
