Hello,
I have a few questions about Tracula. I am very new to DTI, so I hope you can bare with me.
1.) I have been checking my registration at the prep stage. I am very new to this so it may be that I am not looking at the right files.
I looked at my eddy current corrected diffusion data (which I believe is in data.nii.gz in the dmri folder) with the no_dif_brain_mask.nii, and noticed that the no_dif_brain_mask does not cover very well for some of my subjects. Should I individually tailor the Fractional Intensity Threshold for BET mask extraction from low-b images at the prep stage?
2.) In general what files should I be checking at each phase (prep, bedpost, path)?
3.)How do you generate the whole-brain ROIS to guide the tractography (is the white matter mask that is generated at the prep phase involved)?
Thanks,
Emily
