Hi everyone,<br>
<br>
I am trying to use streamtrack (probabilisatic with CSD) on one of
my datasets and get the following error:<br>
<br>

streamtrack is running fine on the original dataset. This is a
resampled image. But the CSD seems to run just finy, only the
tracking fails. <br>
I am using Ubuntu 12.4 and mrtrix-0.2.10_2012-02-10.<br>
Any suggestions?<br>
<br>
Best,<br>
