Dear FSLers,
I am attempting to register ASL data into standard MNI space. We have
scans that are registered to each subject's high resolution T2 mprage, (ie I
have a registration matrix for each subject). The ASL scans are partial
field of view and I have been unsuccessfully attempting to combine, for each
subject, the *manually created registration to T2 matrix* and the *T2 to MNI
matrix* created by flirt and fnirt.
I was wondering if there are issues in combine matrices between partial
field and whole field registrations. Also, I tried to use applywarp with
the -premat option, and this did not work because the registration when
viewed was oriented in many incorrect ways.
In general, does anyone have any suggestions as to what I should do to
make this work? Am I approaching this in the correct manner? I know FEAT
has a bunch of features for this functional data analysis but for straight
registration I shouldn't need FEAT, am I correct?
Thank you in advance for your help!!
