Difference between single-end and pyrosequencing processing?

I have been processing all single-ended sequences using denoise-single. I understand that pyrosequencing is a different sequencing technique than standard methods, but what differences would I expect by processing pyrosequenced sequences as normal single-end?

Hi @michaelsilverstein, have you seen this FAQ about pyrosequencing, on the DADA2 website?


Hopefully that helps answer any questions (if you haven’t spent much time reading the DADA2 docs, I suggest you catch up there, too!).

Hey Matthew,

Thanks for the response. I took a look at the DADA2 documentation, but I’m still confused about the difference between denoise-pyro and denoise-single.

Is it just that the HOMOPOLYMER_GAP_PENALTY and BAND_SIZE arguments are internally set as suggested by the DADA2 documentation?

Yes indeed! Behind the scenes both methods run the same code, just with the adjusted internal parameters tweaked. Hope that helps!
