I've been trying to run dada2 in python, with the sources available in Qiime2. However I have not been able to extend the use of this API. I can't know the arguments of many available methods and functions, for example how I could specify the equivalent of "--p-n-threads" or "--p-min-fold-parent-over-abundance", among others from qiime2 Linux on quiime2 API.

Thanks in advace!

Hello,

please, read the docs on Artifact API. The corresponding API instructions are available in the tab next to the command line interface (CLI).
