Looks intriguing. Would be good to have usage instructions in the documentation. Right now it's not so obvious how to use it. Maybe include some screen shots to show what this would look like with different evocations.

[Garyfallidis]

Run this workflow from the command line in the following way

        >>> dipy_horizon streamlines.trk brain.nii.gz

        or

        >>> dipy_horizon streamlines.tck --cluster --cluster_thr 15

        or if you do not want visual output use

        >>> dipy_horizon fa.nii.gz --stealth

[arokem]

Thanks! I'll give it a whirl.

Do you want to add a page to the documentation with these instructions?

[arokem]

What does it mean that it doesn't have visual output in stealth mode? That it just creates a figure?

Also, I get an output the terminal, like this:

(dipy) sess-01$dipy_horizon dwi_dti_fa.nii.gz

What does that matrix mean? Would be good to provide more information.

[Garyfallidis]

We can add docs later. For now I need this piece merged to support the workshop. After that will work on improving coverage, adding new awesome features and make beautiful docs online. There is plenty of work todo. But we have two important deadlines a) NIH report, b) awesome DIPY workshop! I suggest we just merge for now.

[arokem]

OK. Let's do that. It's looking really good, but there is also some functionality that doesn't work on my end. I'll post issues after merging.

Given that, I think this is ready to go (all @skoudoro's comments are addressed, right?). If no one else shouts loudly, I will merge in a couple of days.
