Hi I used both FSL and FsFast to process a set of fMRI data. after using FSL, I used "reg-feat2anat --feat xxxx.feat --subject xxxx" to check the fMRI to T1 registration in FSL. for some reason, I cannot get the FSL registration to come close to the one done by FsFast (please look at figure at http://web.mit.edu/paymon/www/regis.pdf)
the left most figure, shows the fMRI to t1epi to T1 registration done entirely in FsFast using "autoreg-sess". the two right most figures, show registrations done in FSL followed by "reg-feat2anat --feat xxxx.feat --subject xxxx". Visually, the registration done with FsFast looks much better than the ones done with FSL and then transformed to FsFast. here is my question: should I be suspicious of the my registration process in FSL, or am I not applying reg-feat2anat correctly, and hence causing a poor fMRI to T1 registration. I am using FSL 3.3.7, and FsFast under nmrenv. thanks a lot for your help, paymon _______________________________________________ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer
