Nice change. But I didn't like that it printed the RMSE also within flavor test when there was no difference. So I have activated that only when detailedOutput is on. Because I like to check directly on the screen if the import went fine and there are no errors - without going to the tsv or xls. But if you still want to have that - no problem ;)

Otherwise - if you agree with the change, we can merge...

No, that's perfect 👍
I just wanted to put it in a separate script because I saw that @BeatrizPadrela recently needed a script which basically does exactly this :)
