Thanks Paul, I suspect it's not the realignment per se, but perhaps something else changes in this step to. If I remember correctly I first tried realigning in fsleyes and got the same error, while after realigning with [
neuroanatomy.github.io] things ran without hick-ups. It's probably something stupid, but it would be good to know what's happening. I'm prepping an info package for you with exact commands and the original files.
