External Email - Use Caution
Hi Douglas,
Thanks for your reply!
I tried, but the volume and T1 still don't align.
my purpose:
make a mask of superior colliculus
Here is how I did:
1) tkregister2 --mov T1.nii --s sub01 --regheader --noedit --reg register.dat
2) open freeview and load orig.mgz→ New ROI and select orig.mgz as the template
volume→ draw ROI of superior colliculus slice by slice and save it as sc.label
3) mri_label2vol --label sc.label --temp T1.nii --reg register.dat --o sc.nii
--invertmtx
The problem:
sc.nii and T1.nii don't align, the ROI of superior colliculus are in the wrong
place.
I would highly appreciate If you have any suggestions as the ways to get
superior colliculus' ROI or mask.

Try adding --invertmtx to the mri_label2vol command

Thanks for your reply and sorry to bother you again. The problem is that the
volume converted from label which drew by freeview does not match T1.
Happy Thanksgiving day!

coordinate mismatch
I'm not sure what the problem is. You say that they match when you load the T1
and the sc. If so, what is the problem?

Hello Freesurfer Developers,
I'm trying to get superior colliculus' ROI mannually by freeview. I load
"orig.mgz" as volumes and set the "orig.mgz" as the ROI's template then draw
the ROI and save it as a label file. After that I use "mri_label2vol --label
sc.label --temp T1.nii --reg register.dat --o sc.nii", "T1.nii" is my initial
structure image, "register.dat" got from the code:" tkregister2 --mov T1.nii
--s SUB --regheader --noedit --reg register.dat", and it worked, but the
coordinate mismatch, much different from the SC's position in the T1 space(
Load T1.nii as volume and SC.label as ROI in freeview, and they are matched).
Can anyone help me? Thank you!
