Hi Brian,
yes it looks like this is slightly too small. A little stretching does not hurt. The talairach transform from the base is used for all the longitudinal runs, so if it is wrong, this will have an influence. In your case, however, I think it might not be a big problem (as the difference is really small). You could try both ways (with manual adjustment and without on one or two subjects) and see if it has a big influence. I would be surprised if it did.
Best, Martin

Hi Martin,
I just wanted to get your opinion about these images...It looks like I need to stretch them some so that the green part is in the white brain area. Would you agree?
