[Mrtrix-discussion] tracking with high resolution seed/mask/include

[Maarten Vaessen]

Hello,

i am trying to do a streamtrack with SD_PROB using high resolution seed mask
and include images. The DWI data is at 2mm iso, the other masks are at 1mm
iso from the T1 image, they are from a freesurfer segmentation. I checked
whether all files are in good registration with mrview (and they are).

i run something like: streamtrack SD_PROB CSD_2mm.nii -seed wm_1mm -mask
brain_1mm -include target_1mm -num 10000 tracks.tck

Alas, the program freezes after execution, there are no errors or messages.
Just no output and nothing happens. The file tracks.tck is created on the
hd, although its very small in size (420 bytes).

When i try the same with 2mm mask in DWI space, all runs fine.

I checked the source code to see what could go wrong, all i could find is
that base.cpp makes Mask objects which are in principle Interp objects, so
getting a value from the Mask from a tracking point in mm coords should be
no problem right?

kind regards Maarten
