[Mrtrix-discussion] Course

[J-Donald Tournier]

Hi Francesco,

No, we don't run such courses, I don't think there would be enough demand
for it (?). I do get the odd query on the topic, but that's about it.

That said, I do think it would be good to have a bit more information than
the current documentation (particularly for the MRtrix3 version...). I'm
not sure what people would find most useful. One idea that we'd discussed
in the past was to provide a sample dataset combined with tutorials and
worked examples that people could run through on their own computers. I
think this might be the best way forward, I'll have a look into this when I
have a minute. Those using MRtrix3 will have noticed that we have a wiki on
GitHub, which should allow other users to add to the documentation where
they feel it's lacking (contributions are always welcome!). This would
probably be the most obvious place to expand, especially since development
on MRtrix 0.2.X has been essentially stagnant for the last 3-4 years... If
anyone feel like contributing by adding to the wiki, providing data for a
tutorial, writing a tutorial, or simply expression your opinion on the
topic, please feel free to dive in!

Cheers,
Donald.
