Is it possible to install and run qiime1 and qiime2 environments in parallel?

Hello everyone!

I’m recently considering to start with Qiime2… I work in linux with Qiime 1.9.1 (natively installed), it could be a problem (with compatibility or else) if I install Qiime 2?
Since I’m going to start I don’t like to lose functionability of the Qiime I already have!

I’d like to know if someone did it before or if you know this may be an issue?


Hi @Steph_Hp,
That’s the beauty of working with conda environments, they are self containing meaning you can easily install 10 different versions of qiime1/2 and they will not interfere with each other.
The usual installation guide with Qiime2 puts this into its own conda environment which you can call with source activate <env_name> then deactivate with conda deactivate, run conda enva list to see a list of all your environments and then activate another one from the list as you please.


Hi @Mehrbod_Estaki,
I’m going to try it! Thanks so so much for the answer!
