Hi!

I was looking for an option to check for chimeras in q2. For various reasons I can't use DADA2 and Deblur, and my data do not carry quality information.

Thank you!!

Hi @steff1088,  
Thanks for asking! Not yet, but we have an [open issue](https://github.com/qiime2/q2-vsearch/issues/28) to get a chimera checker added, which should be in this month's release.

I hope that helps!
