... Yes, that is correct. Both scater and scran are completely switching to SingleCellExperiment for the next Bioconductor release. The functions “toSingleCellExperiment()” and “updateSCESet()” in scater will convert an existing SCESet object to a SingleCellExperiment object for you. — Davis McCarthy ...

... Thanks for the bug report! I've just commited (to Bioc devel) fixes for the colSums issues and adjusted read10xResults so that it coerces 10x data to a dgCMatrix automatically. We're still working through all of the other possibilities and adding tests, so the rowVars issue you experienced ...

... OK, you haven’t told us what version of scater you’re using, so I’ll assume it’s the latest version, 1.4.0. From the documentation for newSCESet (Details section): “...an SCESet object will contain exprs values; these will be computed as log2(*pm + offset) values if a data type higher in the hierar ...

... Hi Gabriel I'm not sure that I can describe this more concisely than in the original figure caption: "QQ-plots of goodness of fit statistics using common, trended or empirical Bayes genewise (tagwise) dispersions. Genewise deviance statistics were transformed to normality, and plotted against theor ...

... Hi Assa It is certainly possible and makes sense to use scater for bulk RNA-seq data. I expect that SC3 would also work well on bulk RNA-seq data. The authors of that package could offer more insight, but a priori I think it would perform well in this setting as well. Normalised values (if they ...

... I think I might have found a bug in rhdf5. Namely, calling the following in a session where library(rhdf5) has *not* been run: rhdf5::h5write(donors, file = output_file, name = "sampleID") (where "donors" is a character vector) gives the following error: ` Error in UseMethod("h5write") :   no ap ...

... I absolutely agree with Aaron. Bioconductor 2.8 was released in April 2011, so by using edgeR v2.2.6 you're missing out on almost 6 years of methodological improvements and bug fixes. I *can* remember a time when glmLRT accepted those arguments, but nevertheless strongly advise you to update you ...

... You should use the counts with edgeR. scran computes size-factors for normalization comparable to those from TMM, but with some smart adjustments to appropriately compute size factors from scRNA-seq data with lots of dropouts. As such, size factors from scran are used in an edgeR workflow in the sa ...
