Hello,

I have two versions of DESeq2, 1.14 and 1.16. I run the following code:

dds <- makeExampleDESeqDataSet(n=100,m=12)
dds$genotype <- factor(rep(rep(c("I","II"),each=3),2))
design(dds) <- ~ genotype + condition
dds <- DESeq(dds)
resultsNames(dds)

For the version 1.14 it produces the following output:

[1] "Intercept"  "genotypeI"  "genotypeII" "conditionA" "conditionB"

And for the version 1.16 the following:

[1] "Intercept"        "genotype_II_vs_I" "condition_B_vs_A"

My question is, if on the version 1.16 it is possible to revert to the 1.14 output (single levels of factors) in order to make analysis like DESeq2 likelihood ratio test (LRT) design - 2 genotypes, 4 time points?

You can use
dds <- DESeq(dds, betaPrior=TRUE)

to get the resultsNames to match, but I think if you're doing an LRT test, then it shouldn't make much difference, as the full and reduced models are specified in exactly the same way as before, without referencing specific coefficients.  And if you're doing a Wald test, the same portfolio of contrasts is available (though you may have to 'reword' them in terms of the new, relative, resultsNames), and you can moderate the fold-change (as was done by default in earlier versions of DESeq2) with the lfcShrink function.  I think an advantage of the new approach is that one can shrink the specific lfc one is interested in, which is a good thing.
