Hi,

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](https://forum.qiime2.org/t/reads-processing-with-different-primers/2777/5). 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!

Regards,  
Lilian

Hello Lilian,

Check out the [documentation for q2-fragment-insertion](https://library.qiime2.org/plugins/q2-fragment-insertion/16/) in the Qiime2 library. That includes a tutorial with example commands.

Start with that, and let us know if you have any questions about that tutorial or how to apply it to your data.
