Hi,

I have 3 questions on tracula statistics outputs.

1) There are duplicate points in pathstats.byvoxel.txt, is it normal?
I didn't try it on all 42 tractcs.  For the few I've looked at, they all have duplicate points.
I used the default setting in the config file to run trac-all.

2) When I do along-tract statistical analysis, sig.mgh and z.mgh are 1D files.
When embed the sig.mgh and z.mgh statistical maps from the analysis into the template .trk
(*.display.trk, which is 3D), it seems to me that sig.mgh and z.mgh don't have enough information to give *.display.trk the voxel values for the *.overlay.trk.  There is no one-to-one voxel corresponding between sig.mgh and *.display.trk.  What am I missing?  Or what's the embedding process do?

3) When I convert .trk(*.overlay.trk, for example) to nii.gz or ascii using dmri_trk2trk or
mri_convert the voxel values of the .trk file don't get converted into the .nii.gz or ascii file,
only the x,y,z coordinates are converted.  Is there a way to get the voxels values of the .trk file
when converting to .nii.gz or ascii format?

Thanks,
