Hi team
I am interested to add [SRS](https://github.com/vitorheidrich/SRS) as a plug-in in qiime2 and would be appreciated if you could give me some guidance of how I can implement this as a plug-in in qiime2?
Thanks in advance
Marwa

Hi @MarwaTawfik,
Not to discourage you, but have you seen q2-SRS?
[https://library.qiime2.org/plugins/q2-srs/31/](https://library.qiime2.org/plugins/q2-srs/31/)
Best,
Justine

That is not discouraging, I just don't want to use rarefaction but SRS instead. Thanks for sharing this. I have been using nf-core/ampliseq so they haven't incorporated this yet. Do you contribute too to nf-core/ampliseq upgrades? as they are currenlty only using rarefaction option from qiime2.

Here is my thread awhile ago, regarding this.
Could you please help with the container part?
> I had a short look and found that SRS has an R package and is in conda-forge, see [r-srs - conda-forge | Anaconda.org](https://anaconda.org/conda-forge/r-srs), but I could not find a docker or singularity container, which is a prerequisite to integrate it (might have missed it, also possible to create own container ofc).
> It also doesnt seem to be in any QIIME2 container, see [Index of /qiime2/](https://packages.qiime2.org/qiime2/)

Hi @MarwaTawfik,
Have you looked at this post? It discusses how to install an r package in our docker image: [Install phyloseq in qiime2 docker container - #7 by thermokarst](https://forum.qiime2.org/t/install-phyloseq-in-qiime2-docker-container/2724/8)
Hope this helps!

Hi @MarwaTawfik, You can also check out [_Developing with QIIME 2_](https://develop.qiime2.org/) for general information on creating QIIME 2 plugins, in case that is helpful for you. We should have a how-to article in there shortly that illustrates how to wrap R code in a QIIME 2 plugin. You can track progress on that [here](https://github.com/caporaso-lab/developing-with-qiime2/issues/98).
