Dear All:

I would like to know if to check my DTI's data registration on the anatomical data having the registration encoded in the registration.dat by tkmedit as below:

tkregister2 --mov /media/1Tra/Antonella_2011/DTI_FS/dtrecon/C51_dti.nii.gz --s /media/1Tra/Antonella_2011/DTI_FS/dtrecon/C51 \
 --regheader --reg /media/1Tra/Antonella_2011/DTI_FS/dtrecon/C51_dti/register.dat --surf 

I will see my DTI volume as a fuzzy MOVEABLE volume and  the target will be my anatomical volume?

What will represent the green line?

What is the difference is I run without --s and without --regheader so if I run just:
