I have used QIIME2 and now, I am getting myself familiar for Qiita. I am currently in the process of preparing my data from V3-V4 to only V4 region for meta-analyses on Qiita.
I have checked the previous question on how to do this and I found this. It suggested to use the q2-fragment-insertion. I have go to the link in the Github to learn the tutorial but I do not really understand on how it works - which file to download, which file to open, how to open, etc. Any help would be much appreaciated. Thanks!
