Does this happen on a lot of your subjects? I'm not entire sure why it is happening to this one, but one reason may be that there is more torso (eg, shoulders) than the usual scan. I was able to get it working if I initialized it by hand. This would be ok for one subject, but you would not have to do so with many subjects.

Dear Douglas,
I uploaded the file and the file name is wenzhen.tar.gz. the file has freesurfer_results and template.nii.gz.
Thank you for looking into the problem. Please let me know if you need anything.
Best, Wenzhen

I can't figure out what is going on unless I have the data. Can you upload it? All I need is the subject's dir (output of recon-all) and the template.nii.gz. You can follow the instructions below
From the linux command line, Create the file you want to upload, eg, cd $SUBJECTS_DIR tar cvfz subject.tar.gz ./subject Now log into our anonymous FTP site: ftp surfer.nmr.mgh.harvard.edu http://surfer.nmr.mgh.harvard.edu It will ask you for a user name: use "anonymous" (no quotes) It will ask you for a password: use "anonymous" (no quotes) cd transfer/incoming binary put subject.tar.gz Send an email that the file has been and the name of the file.

Dear Douglas,
Yes, they do look properly oriented to me.one thing I noticed is that when I switch over coronal view, sagittal view, and axial view, brains seem to shift back and forth in horizontal direction. If you see the picture below, brains are not in the same spot. I am not sure if this is an issue.

Is the fmri scan properly oriented? Eg, run freeview template.nii.gz and see of it is oriented correctly in the FV window

Dear Douglas,
I am using freesurfer 6. I used following command to register fMRI data to anatomical scan. $ bbregister --mov sess01/rest/001/template.nii.gz --t2 --s subject --lta register.dof6.lta
I used following command to visualize the output; red: functional scan; overlaid on orig.mgz structural scan. $ tkregisterfv --mov sess01/rest/001/template.nii.gz --reg register.dof6.lta --surfs
It seems like two are not aligning well. Is there any step that I should take to improve? Again, thank you so much for helping.
Best, Wenzhen

What version of FS are you using? Try using bbregister without an init option. Also make sure you are specifying --t2 And send your full command lines next time
