Hello @Hayley_Guay,

I think you are off to a very good start! I can confirm that your imported data looks OK, and you should be ready to proceed with the next steps show in the various tutorials. On to dada2!

Try this thread: [Merging, Quality control and overlapping](https://forum.qiime2.org/t/merging-quality-control-and-overlapping/12618)

Try the original DADA2 docs! Pseudopooling is discussed in ✨ vivid detail ✨ on this page: [Increasing the sensitivity of DADA2 with prior information](https://benjjneb.github.io/dada2/pseudo.html)

I think you are doing exceptionally well, especially given that you are working with ITS data, which can be tricky. Let us know if you have any more questions along the way. :qiime2:
