[Camino-users] Track Images Not Aligned

[Sergio II Ramirez]

Hello,

I'm a research assistant who has been running into some issues as of late
using Camino's 'track' command and have been at a loss at how to proceed,
hoping I can get the help needed here! Apologies if I'm not as well-versed
in the field as others here.

My exact input is shown below:

track -bedpostxdir bedpostx.bedpostX -inputmodel bedpostx_dyad -curvethresh
75 -tracker euler -stepsize 0.5 -seedfile wm_interpolated.nii.gz -header
wm_LR_bin.nii.gz -outputfile header_test.Bdouble

Whilst encountering errors such as these shown below:

WARNING: Seed point
Point3D: (249.5078125, 140.5078125, 50.15000140666961)
 is outside the diffusion image space, ignoring

We're under the assumption that the two images supplied for the '-header'
and '-seedfile' are not aligned properly, even though they both derive from
the same dwi, and any attempts to edit the header for either file to align
them have not provided any changes. If it brings any clarification, we
utilized FSL in order to create the 'wm_interpolated.nii.gz' file supplied,
but again still deriving from the same dwi as before.

Might there be any way to align these two files properly that I am unaware
of? Or are we wrong in our assumption and there seems to be a different
problem at hand? I would greatly appreciate any help on how to progress.

As a side note, from the results I have gathered using the command above
they seem to be lacking a substantial amount of streamlines as opposed to a
colleague of mine who is receiving a larger amount from MRtrix. I'm unsure
if the '-iterations' input is the appropriate method to solving this
predicament, and would appreciate any help on this matter as well.

Thank you for any help that you can provide in my case, it will surely help
the studies we are performing here.

Best Regards,
Sergio Ramirez II
