Hello experts,
Over the years, I have had a number of non-linear (FNIRT) registration fails, which I couldn't fix. It usually happens in brains with relatively large parietal sulci, so it's more common in older folks. I have had the luxury of just dropping those participants. However, I'm running an analysis on a very tight sample right now, so I don't want to drop anybody because of the registration. I'm attaching an image with the problematic registration (I circled the region where I see a problem). It may not look like much on an image here, but it's pretty substantial in FSLView. What are some possible solutions for this?
Thank you in advance.
-Marina
