I am using regularly MRtrix in windows without any trouble. The only thing that seem to be limited is the number of fibers. I tried to get 1 million fibers and it crashed:</div><div style="font-family:arial,sans-serif;font-size:12.727272033691406px">

File was about 2GB. I ran it again with 450,000 fibers and it worked. However, mrview cannot open the .tck file.</div><div style="font-family:arial,sans-serif;font-size:12.727272033691406px"><br></div><div style="font-family:arial,sans-serif;font-size:12.727272033691406px">
What is the limit of fiber number in the Windows version? Is it better in Linux?</div><div style="font-family:arial,sans-serif;font-size:12.727272033691406px"><br></div><div style="font-family:arial,sans-serif;font-size:12.727272033691406px">
Also, is there a way to convert .tck to TrackVis .trk file? I found a python script but needs installation of all sorts of addons that my computer is not liking.</div><div style="font-family:arial,sans-serif;font-size:12.727272033691406px">
