Error while running feature-table heatmap in 2019.1 version


I received an error when I used feature-table heatmap:

Plugin error from feature-table:

negative dimensions are not allowed

Log information:

line 144, in tostring_rgba_minimized

ValueError: negative dimensions are not allowed

I have no negative values in my data, and I kept receiving the same error with all the different command options, and it didn’t change depending on which data I put in, if I provided metadata or not.

I asked a colleague who has previously made some heatmaps, but the error was not something she had seen before. So I decided to try it in the 2018.11 version of QIIME2 before I asked the forum. And in 2018.11 it worked! :smiley:

Bug? :microbe:

Hey there @Elise! Looks like you forgot to include the command you ran --- can you please provide that? Thanks! :qiime2:

I guess I tried so many different variations of the command that I figured it didn’t make sense to add it. Sorry for that!

Here is an example, but I also tried without metadata (and without column), with and without specification of both p-normalize/p-no-normalize, and with all the different method-options and all the different cluster-options.

qiime feature-table heatmap
–i-table collapsed_table_level6.qza
–m-metadata-file metadata.tsv
–m-metadata-column kategori
–p-cluster features
–o-visualization heatmap-genus.qzv

Thanks @Elise! The error above is related to numpy/matplotlib, some of the tools being used behind-the-scenes in this visualizer. A quick google search indicates that this exception might happen when you have an ID mismatch — we can verify by running the following commands:

qiime tools inspect-metadata collapsed_table_level6.qza
qiime tools inspect-metadata metadata.tsv

As well, are there any missing values in the kategori column of your metadata file?

Thank you!

Well, the metadata I’m using has more IDs than the sample I use to make the heatmap. This is what I usually do for other analyses in QIIME2, and it always works fine. Yes, there are missing values in this column of the metadata. You think the error has got to do with the metadata? Why doesn’t it work without metadata, then? (Metadata is optional?) and why does it work in the 2018.11 version?

Call it a “hunch.”

:man_shrugging: Do you get the exact same error when you run it without metadata?

The versions of matplotlib and numpy were updated to the latest releases in 2019.1.

Would you be able to share these files with me? Feel free to send links in a DM if that is preferable. Thanks!

Hi again!

Sorry for the very late response.
Thank you - this clarifies the difference between the qiime2 versions.
About the metadata: Yes, the error (and log) is the exact same.

I will send the files in a DM.
Thank you!

Hmm, I just ran the following command on the files you sent me:

qiime feature-table heatmap \
  --i-table collapsed_table_level6.qza \
  --m-metadata-file metadata_forum.tsv \
  --m-metadata-column exacerb_kategori \
  --p-normalize \
  --p-cluster features \
  --o-visualization heatmap-genus.qzv \

I tried in 2019.1 and the development version of 2019.4 and it ran successfully to completion.

I wonder if your environment has had some modifications, specifically around some of the dependencies… Can you run conda list and paste the results here?

Thanks, dependencies all look fine to me.

Can you please run the command I provided above on the files you shared with me? This is to ensure that you are still seeing the problem on your end, and that it isn’t a data-specific issue (I noticed some filenames changed between your original error and what you sent me).

Hi. I changed the names on purpose, so that was intended. This is what I ran and got:

(sorry for not formatting posts!!!)

Yep - I understood that — my concern was that maybe you copied the wrong files while doing that — making it so that I wasn’t testing the exact same data as you.

A quick google search indicates that this might be a problem with matplotlib with certain rendering backends. Can you run the two commands to follow and paste the results here? Please paste in a code fence, like this:

my pasted results

that way the forum formats it for us. Thanks!

python -c 'import matplotlib; print(matplotlib.get_backend())' 
(qiime2-2019.1) XXXXX:Heatmaps_problems ele010$ env
(qiime2-2019.1) XXXXX:Heatmaps_problems ele010$ python -c 'import matplotlib; print(matplotlib.get_backend())' 

Does it make sense? :slight_smile:


I just realized - it looks like you posted dependencies from the 2018.11 environment, but, my understanding is you weren’t having this problem in 2018.11, but rather, 2019.1. Based on a few quick searches, this issue is almost certainly related to the 3.x release cycle of matplotlib. It is also apparently a host-specific issue (I think) — I can’t reproduce on this end. My guess is the next release of matplotlib will sort this out. You can continue to run 2018.11 for this command if that makes sense.

OK, that is odd - I checked my log, and I did run the command in 2019.1.:thinking:

Thanks for your help and time! It works fine in the 2018.11 version, so I can run there - I just assumed it was something in the 2019.1 version :slight_smile:
