I and one of the other developers of ITSx had a discussion a while ago about that using the --anchor option should output the “anchor sequences” around the ITS regions also for the full-length output file (given that the --truncate option is activated). I have today changed ITSx to employ this behaviour, updating it to version 1.0.9. The update also improves sensitivity when using the --anchor HMM option slightly, and can be downloaded here. Happy barcoding!
