Hi everyone!
I am trying to install q2-picrust2 but it seems to be available only for 2023.2 version. Is there any way to use this as a plugin in the latest qiime2 version (2023.5)
Thanks!
Melisa
Hi @Melisa_Olivelli,
I just tried and I was able to follow the install instructions for q2-picrust in q2-2023.5 so I think it should work for you!
Hi again @cherman2 ,
I installed it from source and the installation was succesfull. But when I run the pytest I got one failure:
=============================================== short test summary info
FAILED tests/test_place_seqs.py::place_seqs_tests::test_run_place_seqs_pipeline_sepp - SystemExit: 1
======================================= 1 failed, 60 passed in 67.13s (0:01:07).
I found on github (pytest error in WSL (Windows Subsystem for Linux) · Issue #182 · picrust/picrust2 · GitHub) that they say that should work if SEPP is the only part of the pipeline that is having issues. This is because the default placement tool used is EPA-ng, not SEPP. The downside is that EPA-ng uses much more RAM.
Do you have any other advice?
Thanks again!
Hello!
First, I would start from a more general question: what is the environment you're working on? Usage of PICRUSt is misleading almost everywhere except human gut.
Cheers

Hi @Melisa_Olivelli, That sounds like it should be fine, as long as you're not planning to use SEPP and it sounds like you're not. Good luck!
Hello! I am analyzing an iron reducers consortium and soil microbiome. Is there any other way to do it? I am completely new to metageomes and only know how to use qiime2 (with a lot of effort and mistakes!)
Thanks!

Hi again @cherman2 !
I tryied to use PICRUSt and it said the plugin doesn't exist. I tried to install it again following the instructions (Manually install QIIME 2 plugin · picrust/picrust2 Wiki · GitHub) and I got the following:
(base) melisa@DESKTOP-IN0O610:~ conda activate qiime2-2023.5

Hi!
Perhaps I got a more straightforward solution, which is installing PICURST2 in MAMBA, much faster than conda. Worth to try.
Hi! I will try that! But can I use the files normally after installing picrust2 using mamba? Sorry about the silly questions but I am completely new at this.
Thanks!
Regards
Hi @Melisa_Olivelli,
Yes! Mamba is a package manager, just like conda is - it just uses a faster solver, so environment creation is usually much more efficient.
Cheers
Hi!
I installed picrust2 with MAMBA. But I guess I am not doing things right to analyze my data. I activated the picrust environment. Put the rep-seqs.qza and the table.qza in the picrust2 folder and used the following commands, with no success. Don´t know what I am doing wrong:
(picrust2) melisa@DESKTOP-IN0O610:~/picrust2-2.5.2$ picrust2_pipeline.py -s PE-rep-seqs.qza -i PE-table.qza -o picrust2_out_pipeline -p 1

Hope you could guide me a little bit further.

Hi @Melisa_Olivelli,
It looks like this is a different error than you were running into previously. Here's where the issue is coming from:
This is occurring when the FASTA file is being read - it seems like there is a stray character, or something that's been malformed with your FASTA file. You could confirm whether this is an issue with picrust2 or your input file by using a different input as a test - something like data from the Moving Pictures tutorial, since we know there aren't any issues with the formatting of any of those data.
Hope this helps
