Hi guys, i want to export the rlog values from DESeq2 or vsd, but i only got the dds counts, using the following script:

countsdds <- counts(dds, normalized = TRUE)
write.csv(countsdds, file="dds_norm_counts.csv")

Is there a way to export rlog values?

Thanks for your help!

Googling rld DESeq2 already gives me the answer, e.g. here

Thank you, WouterDeCoster, but i don't want to apply the functions "rlog" or "vst", I just did that. I want to export the output values after run the function, like .csv or .xlsx format table to my directory.

Right, what about

rld <- assay(rlog(dds, blind=FALSE))

Thank you! I was trying to extract my variance stabilizing transformation and write it to a .csv. Got it to work with this:

vst_write <- assay(vst(dds, blind=FALSE))

write.csv(as.data.frame(vst_write), file="VST_results.csv")
