That's hard as I'll just be guessing. What is the intensity of the wm just inside the white surface where you are missing pial? And why can't you send an image? Cheers Bruce On Feb 21, 2013, at 11:11 AM, melinaki p-t wrote: > I am afraid I can't... > Can you give any advise without pictures?

I don't think either one of these are errors, just warnings that occur pretty frequently and I don't think should impact the results. Does the recon finish? Do the results look ok? On Fri, 22 Feb 2013, Blessy M wrote: I am getting the bottom two sets of errors while doing a simple recon-all.

Hi Andrew, I don't know how the sulc measure gets computed and what it means exactly. Probably someone else can tell. The longitudinal treatment is identical as for example thickness. The slope (rate) is a fit into the data across time. So a negative slope means a reduction in whatever is me
