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

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
