Problem with Filter Table command


I am trying to make a filtered table which only includes the phylum Cyanobacteria, so I run the following Filter Table command with the following parameters:

qiime taxa filter-table
--i-table table.qza
--i-taxonomy taxonomy.qza
--p-include p__Cyanobacteria
--o-filtered-table table-phylum.qza

And I get this error message, which the terminal can't show completely.

It's not a plugin error as I retried using a similar command in the tutorials and my input files seem to be in order.

Help, please?

Hello @PabloCL! Sorry to hear things aren’t going well.

Do you see that little orange rectangle in the bottom right corner of the window, just above the letters “DERECHA”? That is the terminal’s scroll bar, you can click and drag that up and down to see the history in your terminal session. Also, the full error log is saved in the file /tmp/qiime2-q2cli-err-dtsxitio.log (this file will be different for each command log, it is a rotating temporary file).

On to the specific error, without seeing the entire thing, I might be barking :dog: up the wrong tree :deciduous_tree:, but it looks like an issue with missing feature IDs from your feature table in your taxonomy file. I can’t be certain without seeing the beginning of the error message, though.

If the ID suggestion doesn’t set you on the right path (for example, maybe you mixed up files and used the wrong table or taxonomy?), please attach the error log, or a screenshot of the beginning of the error message, that way we can get to the bottom of this! Thanks! :t_rex:

Hello, @thermokarst.

The error message in this case is so big it won’t show up completely even if I go all the way up in the terminal window. It’s all just a big string of what seems to be Feature IDs.

Anyway, I checked the error logs and now know what seems to be the problem. I used the taxonomy artifact generated in the MP tutorial since when I used the following command:

qiime feature-classifier classify-sklearn
–i-classifier gg-13-8-99-515-806-nb-classifier.qza
–i-reads rep-seqs.qza
–o-classification taxonomy.qza

…on my own rep_seqs.qza artifact, it results in the following error.

So… It all seems to boil down to insufficient memory allocated to my VM. It’s no wonder I’m getting nowhere with filtering my table seeing as my taxonomy file is not the proper file for my table.

I don’t know what I was thinking, silly me :sweat_smile:.

I’ll fix the memory issue then get back to it. Thanks a lot for the help and the patience :+1:.
