Hmmm, can you upload a couple of examples?

Here's one that mislabeled parts of the CC as left cerebral white matter at the center slice:

You can see the light purple blotches above the caudate (light blue); those are labeled as white matter hypointensities.

The overall quality is not great, but we're trying to make the best of what we have. Any advice on correcting these common problems in our dataset (apart from manually doctoring them) would be greatly appreciated!

Hi Warren

can you send us some images to show us what you mean? Or upload an example dataset for us to look at?

Hello, In a number of our subjects I've been finding white matter hypointensities around the anterior edge of the caudate, as well as mislabelings of the corpus callosum as cerebral white matter (at and/or around slice 128, sagittal). Has anyone else encountered these problems, and are there fixes that don't involve manually doctoring the mislabelings (such as setting a particular flag for recon)?

I am quite new to FS so please forgive any rudimentary misunderstandings.

Thank you!

Warren
