Detected zero variance balances while performing "gneiss ols-regression"

[mortonjt (Jamie Morton)]

@dheeman00, looks like you will need to filter out those zero-variance features. I'd take a look at the qiime feature-table filter-features command

There are a couple of posts that discuss this problem in more detail

Integer division or modulo by zero Error

Hello, After running gneiss I identified two outliers by looking at the residual plot and also at the proportion plot. I wanted to remove them from the analysis because they are quite different values from the rest so I filtered those two samples from the table with: qiime feature-table filter-samples --i-table f-table.qza --m-metadata-file Mapping-file.tsv --p-where "SampleID IN ('1157B_FR900_T4', '1162B_FR900_T2')" --o-filtered-table gf-table.qza and then rerun gneiss, but when I run the re…
