Hello there, my name is Ignacio Osorio Wallace, I'm an electronic
engineer student at Concepcion University (Chile). I'm currently working
on the creating of a software that could use your library to reconstruct
and segment brain fiber from the NIfTI1Image objects.
I followed your examples to get a hint of how to work with Dipy. And I'm
having some problems with the QuickBundle. The specific problem is shown
here:
"""
Traceback (most recent call last):
File "/home/cocobio/MEGA/2015/Python/Project/segment_quickbundles.py",
line 43, in <module>
clusters = qb.cluster(streamlines)
File
"/usr/local/lib/python2.7/dist-packages/dipy/segment/clustering.py",
line 459, in cluster
ordering=ordering)
File "dipy/segment/clustering_algorithms.pyx", line 111, in
dipy.segment.clustering_algorithms.quickbundles

dipy.segment.clusteringspeed.QuickBundles.assignment_step
(dipy/segment/clusteringspeed.c:3840)
ValueError: Data features' shapes must be compatible according to the
metric used!
"""
I think I'm not doing anything wrong, since this is the example code
provided by the Dipy web-page. The reconstruction and tracking using ODF
is working perfectly.
If you could help in any way, I will greatly appreciate.
Thanks for your time. And I hope my English didn't sound to casual.
Ignacio Osorio Wallace.
