Just to complement this answer perhaps worth checking this other discussion:

> I have two sets of data (paired reads), with two different primer sets (341/806 and 515/806) that I need to combine. I would like to try trimming my 341/806 set to 515/806 but I'm not sure how to go about doing so before pipelining into dada2. Thank you! Julie
