Hi @ebolyen, I cannot reproduce the same problem with the moving pictures tutorial.  
I started running both my data and the moving pictures in two different terminals. The output of the tutorial looks fine:

My data is still running. If I get another error I will post here. I went back and my demultiplexing files look ok:

A while ago I had DADA2 give me errors and @jairideout helped me in this post: [DADA2 error (return code -5) - #10 by jairideout](https://forum.qiime2.org/t/dada2-error-return-code-5/1422/10)  
Maybe something similar is going on this time around?

Thanks again!!
