I want to proceed with dada2.
I want to cut the front part of 20base. How do I set it?

Hi @kimshinseung,
You probably want to use q2-dada2’s --p-trim-left-f parameter.

A couple of clerical notes:
Questions about how to perform analyses should be placed in the General Discussion category. See how to categorize your posts.

As was mentioned in this post, there is a lot of good information in the tutorials. Additionally, most common questions about QIIME 2 have been answered multiple times on these forums. The search bar at the top of the page is a powerful tool. If you think someone else might have run into your question before, please take advantage of these resources prior to posting.



Hi @kimshinseung,

Can i add that the help documentation is fabulous for the CLI API and super easy to use. You can just pass the name of the command followed by the --help flag. So, in your case, you can get the information from the command,

qiime dada2 denoise-single --help

NGL, I think I have the help documentation to get the flags right open basically every time I run a new command.
