While processing a normal brain through fsv5.0.0, an unfamiliar message popped up in the screen output (see below). Any ideas what I should do about this message (anything in particular I should check)?
Many Thanks, Jenifer

Hi Jenifer
we see that sometimes too, and it's never clear why. It's from an open source minimization function and doesn't usually mean anything bad. Check the talairach_with_skull.lta visually and see if it is ok cheers Bruce
