It seems to me that it is not accessible from ensembldb, at least I couldn't find it in the available "columns"... For example, for the gene "Cntnap1" I would like to ...

limma: percent of variance explained
... Dear all, I am analyzing an RNA-seq experiment with voom+limma. The design of the experiment had two fixed effect factors that I combined into one vector including all combinations of the levels of the 2 factors (as explained in the limma user guide, section 9.5), and a random effect that I model us ...

Here are some more details: # dge is my DGEList object with RNA-seq count data y <- predFC(dge, prior.count=2) # When I run a PCA on this matrix, I can obse ...

voom and RPKM for multi-species RNA-seq analysis
... Dear all, I am analyzing RNA-seq data generated from liver samples in two species, human and chimp, with 4 biological replicates in each species. I have mapped the reads to 1-to-1 orthologous exons, and I'm aiming at detecting DE exons between species. After reading the "voom" paper (http://www.stat ...

topGO enrichment using ensembl gene list
... Hello list, I am using the package "topGO" to analyse GO enrichment of gene sets: My genes are ensembl IDs and are not taken from a microarray, so I had to feed "topGOdata" with a gene2GO list. (see http://thread.gmane.org/gmane.science.biology.informatics.conductor/14 627) I construct that list b ...
