Hi Desiree - It looks like this is happening for the corticospinal tract. Is there anything going on with that scan in the area of that tract, let's say slices cut off from the top of the motor cortex or from the brainstem?

The following (with updated number of tries) keeps appearing in the terminal: WARN: Could not find satisfactory control point fit - try 288 Finding center streamline INFO: Step is 5 voxels WARN: Turning off deviation check for center streamline INFO: Step is 5 voxels WARN: Turning off FA check for center streamline INFO: Step is 5 voxels I've attached the log here. Previous communications I've seen regarding this are years old and were solved by upgrading to 5.3. However, I'm already using the 64 bit 6.0. Advice regarding this situation would be greatly appreciated. Thank you, Desiree Lussier
