Dear Marina,
can you please let me know exactly how you ran fnirt on your data, i.e. the command lines for flirt and fnirt? Also, are you running it on non-betted data?

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?
