Is there a data package containing complex RNA-Seq data?
... Does anyone know if there is a good RNA-Seq data set that is reasonably large and has multiple factors included in its metadata? For instance, the airway data set mentioned here, http://www.bioconductor.org/help/workflows/rnaseqGene/#starting-from-count-matrices , is nicely formatted for what I hop ...

DESeq failure after update: unable to find an inherited method for function mcols for signature Rle

I'm running DESeq2 and just updated all of my packages.  Now suddenly I can't run several DESeq functions, rlog, varianceStabilizingTransformation, and DESeq functions now all throw this error.     Here is my session info:   > sessionInfo() R version 3.4.0 (2017-04-21) Platform: x86_64-apple ...

Comment: C: What causes this DESeq2 error at "fitting model and testing"?
... Ok great, that's good to know.  So assuming the "estimating dispersions" goes through, for future reference for anyone who encounters this problem, try VST instead of rlog, and update your R packages.   My guess is that the rlog might have failed somehow in the larger data set, if I had to guess wh ...

Comment: C: What causes this DESeq2 error at "fitting model and testing"?

I did receive the following warning, but maybe it's okay.   27 rows did not converge in beta, labelled in mcols(object)$betaConv. Use lar ...

What causes this DESeq2 error at "fitting model and testing"?
... I am using DESeq2 on a pretty large dataset.  I have mock and infection conditions for several mouse lines at 3 time points.  My goal is to contrast each line at each timepoint with it's corresponding mock at the same timepoint.  Previously I split the data into smaller subsets by line, but now I'm ...
