So upstream seems to be working well, I have run into an issue where the estimatesizefactors is returning a strange error. Input is:

dds <- dds[ rowSums(counts(dds)) > 1, ]

cts <- counts(dds)

geoMeans <- apply(cts, 1, function(row) if (all(row == 0)) 0 else exp(mean(log(row[row != 0]))))

dds <- estimateSizeFactors(dds, geoMeans=geoMeans)

This returns the error

> Error: all(!is.na(value)) is not TRUE

This results in a downstream error of:

>estimating size factors Error in estimateSizeFactorsForMatrix(counts(object), locfunc = locfunc, : every gene contains at least one zero, cannot compute log geometric means

Ran the following to troubleshoot:

traceback()
table(rowSums(counts(dds) == 0 ))
table(colSums(counts(dds) == 0))

Resulted in :

> traceback() 6: stop("every gene contains at least one zero, cannot compute log geometric means") 5: estimateSizeFactorsForMatrix(counts(object), locfunc = locfunc, geoMeans = geoMeans, controlGenes = controlGenes) 4: .local(object, ...) 3: estimateSizeFactors(object) 2: estimateSizeFactors(object) 1: rlogTransformation(dds) > table(rowSums(counts(dds) == 0 ))

Don't See any zero numbers in the tables so I am unsure as to what is causing this error. The fix of removing all values less than 1 should have fixed it no? Please advise.

Can you try estimateSizeFactors(dds, type="poscount")?

This was implemented recently, although proposed a while ago on phyloseq/DESeq2 forums, and hopefully avoids users having to do their own estimation of the geometric means, etc.

Hi,

I got this error, and tried estimateSizeFactors(dds, type="poscount"), but that error is still there. If I add 1 to each cell of the count table, the error is gone. Is it valid to just add 1?

Thanks! Leran

I wouldn’t add one. If you have no genes without 0s, it may indicate you should be using a different scaling factor procedure. Is this single cell or microbiome?

this is microbiome 16S data

I don't think DESeq2 is appropriate for microbiome (there are a couple of threads on this).

If the size factor doesn't work, neither will the downstream steps.

Thanks Michael, I double checked and found that there are 4 samples are with 0 taxa. When I remove them, the software works fine!

Check to make sure all of the column sums of your count matrix are non-zero. I encountered this error and eventually figured out that it was due to a typo in my sample sheet (a misnamed sample ended up with all zero counts).
