Technical Support

Hi,

I am trying to build a linear model using balances (correlation-clustering). When running the following code, I get the error below:

qiime gneiss ols-regression --p-formula "Time_point+Time_days+Subject" --i-table balances.qza --i-tree hierarchy.qza --m-metadata-file metadata.tsv --o-visualization regression_summary.qzv

Plugin error from gneiss:

integer division or modulo by zero

Debug info has been saved to /tmp/qiime2-q2cli-err-6us5_kjy.log

balances.qza (24.4 KB) hierarchy.qza (11.0 KB)

Thanks a lot in advance,
Celia

Hi @cdl,
Check out this topic in the forum archive for troubleshooting support:

Sounds like this error usually occurs when your inputs contain too few samples and/or low abundance/variance features. You may want to filter your tables before using gneiss.

Good luck!

Hi Nicholas,

Thank you for pointing this out! I will check again my tables then.

Best,
Celia
