A user informed me of unexpected behavior regarding potentially chimeric sequences in ITSx, and indeed it turned out to contain a bug that over-reported potential chimeras. This bug is totally unrelated to the new version released this week, and exists in all prior ITSx versions. I strongly encourage everyone to update to ITSx 1.0.6.

I would also like to underscore that ITSx is not a chimera-checker. It detects when sequences look unusual, but all such cases should be further investigated. If you follow this practice, you will see that in some cases ITSx might have over-reported chimeras, and in some instances it will have been correct in its suspicions (and thereby you would be largely unaffected by this bug).
