Hi David, Thanks for the information. We had actually been using layer 4 as the surface but I thought that since atlases are based on MRI mid-thickness it would better to use mid-thickness. But I take your point about histology quality and alignment accuracy being a much bigger source of error.

Hi, I'm working on constructing brain models from histological sections with cortical areas demarcated. Until now we've been writing our own progrms to achieve this. I'd like to start to use Caret for more of this work so non-programmers can do it and our data is more compatible with other datas
