[Mrtrix-discussion] streamtrack segmentation fault

[Peter Neher]

Hi everyone,

I am trying to use streamtrack (probabilisatic with CSD) on one of my 
datasets and get the following error:

streamtrack [DEBUG]: reading key/value file "/etc/mrtrix.conf"...
streamtrack [INFO]: opening image "CSD4.mif"...

streamtrack SD_PROB CSD4.mif fibers.tck -seed seed.mif -debug &>log.txt

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.
I am using Ubuntu 12.4 and mrtrix-0.2.10_2012-02-10.
Any suggestions?

Best,
Peter
