It kind of depends on what is going to happen next. The talairach transform is only used in a couple of contexts: to compute the estimated intracranial volume and when doing volume-based analysis of subcortical structures in FS-FAST. It would also be used if you report tal coordinates for the individual (unlikely) or if you create a group average subject (also unlikely). If none of those apply to you, then I would leave it the way it is. If those do apply, then I would improve it.

Hi Bruce,
Thanks! I looked at the other slices and they look similar to the screenshot I sent you; to my untrained eyes they look like they could use a slight rotation and shift. I am assuming that means it is a reasonable registration.
However, I am not sure how much a talairach registration needs to be "off" before I need to fix it. The examples at https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/Talairach_freeview clearly need fixing. Are there any examples somewhere that show more marginal cases?

It looks a little off to me, but I am not sure from reading the instructions on https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/Talairach_freeview whether the degree of difference I am seeing is to be expected or not. I've attached a screen shot.
