thanks

Hi Doug,
I definitely can. I cannot use FTP from this computer for some reason. Can I upload it via filedrop and should I send it to your email?
Thanks,
Emily

I'm a little surprised you are getting them so frequently. Can you upload a couple of subjects so I can take a look?

Hi Doug,
I am using V6.0.0 (x86_64) on Ubuntu. Should I not be getting these errors so often?
Best,

Hi Emily
it is a segmentation error, but it's a pretty small one. It will mess up the thickness in a region a few mm^2. You could fix it by editing the wm.mgz if you really care about that spot

Hi Doug,
Thank you for getting back to me. I've attached two images (Slice165 and Slice166) with an arrow pointing to the location. I am new at this, so maybe I am wrong and it is not a segmentation error.
I've also attached an additional image (Slice185) of what I think is a type of topological error that I often see multiple times in a subject. Is this a topological defect? If so, if it is only over 3 slices does it need to be corrected?
Thanks again,

sorry, what kind of errors? I could not really tell from the images what the problem was

Hi FreeSurfer community,
I am working on elderly subjects and have had this kind of surface error quite often in different locations. Usually, it's over about 3-4 slices (in one view) and can be fixed, but I am finding multiple in almost every subject and therefore taking a lot of time to edit (and then once reprocessed new ones sometimes come up in different locations). I was wondering if these are normal to have, minor surface errors that do not necessarily need to be fixed. I have added images of an example below. Here are some of the values I get from aparc.stats for caudal middle frontal lh after manually editing:
Surface area: Original - 2500 mm^2 Edited - 2532 mm^2
Grey volume: Original - 1710 mm^3 Edited - 1727 mm^3
Thickness avg Original - 4455 mm std: 2.371 Edited - 4445 mm std: 2.365
Although the thickness values only differ by 10 mm, we are a little concerned because the difference is not within the standard deviation.
Please let me know if all of these errors should be edited or if it may be okay to keep the smaller segmentation/topological errors as they are.
Thank you,
Emily
