Hello FSL experts,
I'm a long time user of FSL and a registration problem that I'm eager to get your feedback on.
I'm running a resting state functional connectivity analysis that requires a very careful registration of the functional and structural images within subjects, particularly around the ventricles. I'm currently running everything in the feat gui and see that a 6 dof (as well as a 12 dof) transformation does a reasonable job of lining of a subject's structural and functional images to one another as a whole, but are relatively poor in the alignment of the ventricles.
Are there steps I can take to improve this?
I'm hopeful that I can simply work in additional improvements/updates to the registration using updatefeatreg.
Many thanks in advance,
Lara
