Aldex2 Error: Not Recognizing Condition

And thanks for the reply 
Unfortunately download date doesn’t necessarily matter, sometimes conda will grab different versions of things. Please provide the information I requested above, that way we can assist you!
Hi @Kristina_Feye,
Thanks for posting, you are the first to catch a bug!
The parameter --p-condition was recently changed to --m-metadata-column (thanks @fedarko !) and I did not update the tutorial (or apparently the conda release) to reflect that. This has been corrected. If you remove the plugin and reinstall, it should now work using the correct --m-metadata-column parameter. I have also updated the tutorial to reflect this. The updated q2-aldex2 version for this bug fix on conda is 0.1.1.
Thanks for catching this and let me know if you encounter anymore issues! I will also be working on the to improve consistency with the Github wiki.
Cheers,
Dan

How do I directly remove a plugin? Also, I downloaded from your github site last week, I should probably remove that build as well.
Understood. I also tried to download Aldex2 from github a while back.

It looks like it is version 1.14.1 that I was running. I have not updated the plugin.

Awesome, thank you! I will try this during the weekend. I am really excited ya’ll have this ready to rock! I’ve appreciated ALDEX2 for a while.

Hi @Kristina_Feye,
You can remove it using conda remove -n qiime2-2019.7 q2-aldex2 (assuming your environment name is qiime2-2019.7), then reinstall using conda install -c dgiguere q2-aldex2. This should work!
Cheers,
Dan

I don’t need to update this in R as well, do I?
Thank you!

It doesn’t require the R package to be updated, but it is always a good idea to make sure you have the most recent version installed!

Thank you for sticking with it and letting me there are issues!
The differentials.qza file must not have the “diff.win” column. If you export the differentials artifact using qiime tools export --input-path differentials.qza --output-path exported-table, you should have a file under export-tabled/differentials.tsv that looks something like this (with differental featureid names of course):
| featureid | rab.all | rab.win.subject.1 | rab.win.subject.2 | diff.btw | diff.win | effect | overlap | we.ep | we.eBH | wi.ep | wi.eBH |
|---|---|---|---|---|---|---|---|---|---|---|---|
| #q2:types | numeric | numeric | numeric | numeric | numeric | numeric | numeric | numeric | numeric | numeric | numeric |

Can you check to see what the differentials.tsv file looks like?

Sorry for it being sloppy, but yes that is my only set of headings. I ran glm. =(

The reason for this bug is because the glm function currently does not have a visualizer (yet). I realize there is an option to allow glm as the test parameter, it should have been noted that it is currently for future use only.
For now, the best way to plot would be to export the differentials artifact and manually plot with python or R. I will work on getting this into the package, and post when it has been included! I’m sorry this wasn’t noted!
Thank you for reporting these bugs,
Dan

No worries. =)
Will it work for the t-test then?
Yes, the aldex-effect-plot visualizer will produce output!
Great, thanks!
I will try R, but my R skills aren’t great yet. I am obsessed with using this plugin as it is really good for this kind of data. Ttest it is =)
Do I need to split it into two levels? I have four levels, with 1 level being a control? Or will it do pairwise associations between each level? Your R documentation seems to be a 2 level analysis.
Just to let you know, your program is AMAZING! I love it, I love the output, and I love how clean the analysis is.
Bravo to you and your team!
