were your images sagitally acquired time series?

Everything should work fine with either radiological orientation or
neurological orientation. This recent bug was the only exception
I know about. So I wouldn't worry - the website warning is not
really necessary anymore, although we internally always use
radiological, so it gets tested a bit more. However, all the tools
have gone through tests for both neurological and radiological.
This latest problem was just an isolated oversight - sorry.
All the best,
