Dear Sir,
I tried to perform a nonlinear registration on an image downloaded by OASIS.
I followed the instructions in
http://www.fmrib.ox.ac.uk/fslcourse/lectures/practicals/reg/index.html
I compared the "registration quality" between my registration and those
obtained by using the data in
fsl_course_data/reg
making a joint histogram both between the images fnirted_old_subj and
MNI152_T1_2mm
and MNI152_T1_1mm and highres_flirted_old_subj.
I observed a good registration when using the image gave in the course,
while I obtain a scarce quality when using my image.
Another, I have already bad results in the linear registration phase
(flirted images).
So I tried to modify the bet command needed to skull strip the subject
changing
bet old_subj old_brain -f 0.35
with
bet old_subj old_brain_032 -A -R -S -B -f 0.32 -g 0
but I don't get much.
Please, help me.
Best regards
