Question

Using the batch-corrected read counts with batch as a covariate in the design formula, perform a sex-specific (M vs F) differential expression analysis (abs lfc>0.5, basemean>10 and using lfc shrinkage), what is the log2 fold change of FAM138A? Use pydeseq2 with default shrinkage method.

Accepted answer
(-0.07, -0.05)
Domain

Why it missed

Resource-driven scientific changeAfter the full PyDESeq2 fit exceeded the 3 GiB memory limit, this run added a low-count gene filter. That changed the gene population used by apeglm and shifted the reported FAM138A coefficient.
