QIIME plugin error from mmvec

jhaffner09 · September 24, 2020, 3:31pm

Hello,

I’ve been trying to use the emperor plugin to create heatmaps from mmvec using the tutorial posted on github (https://github.com/biocore/mmvec). My code is:
$ qiime mmvec heatmap --i-ranks ranks.qza --m-microbe-metadata-file taxonomy_v2.tsv --m-microbe-metadata-column Taxonomy --m-metabolite-metadata-file metabolite-metadata-v2.txt --m-metabolite-metadata-column Compound_Source --p-level 5 --o-visualization ranks-heatmap.qzv

Plugin error from mmvec:

index 0 is out of bounds for axis 0 with size 0

I went to the Q-Tips meeting previously to help identify the problem and they found mismatched names between my taxonomy file and the ranks file. I’ve since fixed those names and everything should be correct, but I’m still getting the same error. From what I can tell, the same names are used for the feature tables and the metadata. Could someone help me figure out what’s causing these errors?

Hi @jhaffner09, what does this command return if you run it with the --verbose flag?

qiime mmvec heatmap --i-ranks ranks.qza --m-microbe-metadata-file taxonomy_v2.tsv --m-microbe-metadata-column Taxonomy --m-metabolite-metadata-file metabolite-metadata-v2.txt --m-metabolite-metadata-column Compound_Source --p-level 5 --o-visualization ranks-heatmap.qzv --verbose

Just to confirm are your sample names between your two datasets matching?

There is also some filtering that is also done internally - samples / features that don’t pass a certain read depth filter criteria will get thrown out. So you may want to check the --min-feature-count and --min-sample-count options (see qiime mmvec paired-omics --help for more options).

Feel free to post your files, since that could help with debugging.

There was an issue with loading the file taxonomy_v2.tsv as metadata:

  Metadata file path doesn't exist, or the path points to something other than a file. Please check that the path exists, has read permissions, and points to a regular file (not a directory): taxonomy_v2.tsv

  There may be more errors present in the metadata file.

When I started preparing the files for mmvec, I matched the sample IDs between the 16S and metabolite data, so those should be correct. I've also confirmed the "taxonomy_v2.tsv" is in the correct directory with the other files. I had a previous error that was caused by mismatched names between the taxonomy file and the conditionals.tsv file, but since fixed that. I checked to make sure all the other names matched, but I might have missed something or formatted something incorrectly.

I tried to format everything similar to the tutorial files provided in the github. My metadata files used in the previous commands are here: metabolite-metadata-v2.txt (339.2 KB) taxonomy_v2.tsv (608.0 KB) . When I tried uploading the qza files, I got an alert saying I could not post more than two links (since I'm a new user). So, I'll try posting those in a separate comment below.
Thank you,
Jacob

My qza files are large and exceeded the limit for a post, so I created a shareable OneDrive folder: https://sooners-my.sharepoint.com/:f:/g/personal/jacob_haffner_ou_edu/EgkJNQUL-sRGpLYOtkKVK38BCMZiR8-rOCl7qKsXO20A1A. Let me know if there are issues with the OneDrive link and I can try fixing it. Sorry for any confusion and thank you for your help.

Best,
Jacob

mortonjt · September 26, 2020, 11:45pm

Hmm. The error says that the file doesn’t exist.
So I wager that it is still the problem.

If you ls that file path, does it say the files exists?

Or maybe you need to explicitly import it as a Taxonomy type via qiime tools import --input-file taxonomy_v2.tsv...

I’d double check the taxonomy format

jhaffner09 · October 8, 2020, 10:55pm

I tried ls in the terminal and it reported the taxonomy_v2.tsv file is in the current working directory, so I’m not entirely sure why QIIME is saying it is not.

I tried importing the file as a Taxonomy type (I was not sure what format best fit, but I went with FeatureData[Taxonomy] – this is a metadata file, but that category seemed most suitable):
$ qiime tools import --type FeatureData[Taxonomy] --input-format TSVTaxonomyFormat --input-path ./taxonomy_v2.tsv --output-path ./TEST.tsv
Imported ./taxonomy_v2.tsv as TSVTaxonomyFormat to ./TEST.tsv

I then tried the first command again and got this error:

I got the same error when using taxonomy_v2.tsv instead of TEST.tsv.qza. Did I pick the wrong format when importing, or is there something else I need to fix?

Thank you!

alright, there is probably something weird going on in your files…

What does the first few lines of your taxonomy_v2.tsv and metabolite-metadata-v2.txt look like?
Your error suggests that something is mislabeled - so either your microbe ids or your metabolite ids are not matching.

Running the following, these are your microbe/metabolite ids in your tables

from biom import Table
import pandas as pd
import qiime2
art = qiime2.Artifact.load('metab_feat_qiime2.qza')
met = art.view(pd.DataFrame)
art = qiime2.Artifact.load('microbe_qiime2.qza')
micro = art.view(pd.DataFrame)
print(met.columns[:10])
print(micro.columns[:10])

Metabolite ids
['1', '3', '4', '5', '6', '7', '9', '10', '11', '12']
Microbe ids
['Parse2906', 'Parse612', 'Parse28', 'Parse1256', 'Parse1026', 'Parse1939', 'Parse2740', 'Parse843', 'Parse1031', 'Parse797']

So somewhere, your microbe ids got fudged and probably don’t agree with your taxonomy output (you should be having hashes). I think you’ll also have issues with taxonomy barplots given the tables you shared.

jhaffner09 · October 21, 2020, 11:24pm

Okay, so if I’m understanding correctly, there’s mismatched names between the microbe feature table (.qza) and my metadata? Specifically, the taxonomy names don’t match the provided IDs? If that understanding is correct, is this something I can fix in the metadata tables themselves or will I need to redo some of the mmvec analyses I’ve done so far? I thought I had identified and fixed a mismatched name issue previously, but perhaps that just made things worse.

Here’s what my metadata files look like when checking the first few lines:

Hi @jhaffner09, sorry if this wasn’t clear before, but your FeatureIDs don’t look like they were generated from a standard qiime2 workflow.

How did you perform your taxonomy classification and denoising? Did you perform these outside of the qiime2 workflow?

If you haven’t already, I’d recommend to check out the Moving pictures tutorial, in particular running DADA2 / Deblur and Taxonomy classification

Hi @mortonjt, these files were created from a QIIME1 workflow. These 16S data were part of an earlier analysis from a few years ago and we wanted to try sticking to that original analysis as much as possible, so the files were reprocessed using the QIIME1 pipeline. So, things like taxonomic classification were done outside QIIME2. When preparing files for mmvec, I converted the new QIIME1 files to QIIME2 formats (ie, biom --> qza), but hadn’t considered that this might affect mmvec. Thank you for catching that – I will process these files through the QIIME2 workflow and get back to you.
