Installer crash on python 3

[samuelstjean]

Simple answer would be the distribute file needs an update, or maybe just remove it as it is pretty standard to have that nowadays (I'll probably od that on my side also).

Works fine on python 2 though.

Same error here @MarcCote

[samuelstjean]

Easiest to make it work is probably to strip out the file, I doubt marc-alexandre still fixes stuff in this as it's getting quite old.

[tashrifbillah]

strip out?

[samuelstjean]

Well, download the release/clone the master, kill off the distribute_setup.py (as it is probably included nowadays), install the rest as usual.

[MarcCote]

Hi @tashrifbillah, tractconverter has been deprecated in favor of Nibabel for anything related to .tck or .trk file formats. Are you using the .vtk file format?

[tashrifbillah]

Hi @MarcCote ,

So, my task was to find a converter that can do trk to vtk file conversion. Googled, and found your repo. Gave it a shot to see if I can install w/o outstanding issues. Experiencing one, followed @samuelstjean's suggestion to omit the distribute_setup.py file. Then, I encountered a number of Py2 vs Py3 issues. Finally, gave up.

But based on your comment, it looks like we can't use your converter to convert trk to vtk anymore, right?

[MarcCote]

VTK format is very generic, different softwares might have different conventions on how to store streamlines information. So, it is not guaranteed that tractconverter will be able to convert them but it worth a try.

I think the fastest and easiest would be to run it with Python 2. This can be done using Conda environment and installing tractconverter in a Python2 environment.

What software will read the .vtk?
