Hello, i need some help, although i have raised a related query before and got a solution from this forum, I am encountering an error when i try to import my paired end reads.
The three bytes: ef bb bf are tripping up QIIME 2. Unfortunately these bytes are invisible so they are tricky to remove. I've gone ahead and stripped them out for you, let me know if this file works better
To be honest I'm not sure, the BOM in this case is just a convention that indicates the bytes following it are UTF-8. This isn't typically used, and usually only happens if software is converting between encodings and "feels like" adding that.
I do know that if you use Excel and export as a UTF-16 text file you will get a similar issue, but it's not actually the same BOM sequence as what you have. So I can't really say how it got in there in the first place. Generally you want to be saving files in the "plainest" text you are able to (UTF-8 is good, and so is ASCII, anything else is likely to have hiccups like this).
Not an awesome answer, but the real solution here is for us to change QIIME 2 to stop worrying about those byte sequences. They don't mean anything and can be ignored, we just need to tell the computer that's what we want to do.
