What is a Bioconductor package?
Bioconductor is a free, open source and open development software project for the analysis and comprehension of genomic data generated by wet lab experiments in molecular biology. Bioconductor is based primarily on the statistical R programming language, but does contain contributions in other programming languages.
What is the Limma package?
limma is an R/Bioconductor software package that provides an integrated solution for analysing data from gene expression experiments.
How does Limma Voom work?
The voom method estimates the mean-variance relationship of the log-counts, generates a precision weight for each observation and enters these into the limma empirical Bayes analysis pipeline. This opens access for RNA-seq analysts to a large body of methodology developed for microarrays.
What is a Limma?
Definition of limma 1 in ancient Greek music : a semitone in the Pythagorean scale that is less than half a whole step and is designated as the difference between a perfect fourth and two whole steps or 256/243.
What can I do with Bioconductor?
Bioconductor provides access to powerful statistical and graphical methods for the analysis of genomic data. It also facilitates the integration of biological metadata like GenBank, GO, LocusLink and PubMed in the analysis of experimental data.
How many Bioconductor packages are there?
The current available version of Bioconductor (Version 3.6) consists of 1477 software packages.
What is Limma used for?
Limma is a package for differential expression analysis of data arising from mi- croarray experiments. The package is designed to analyze complex experiments involving comparisons between many RNA targets simultaneously while remain- ing reasonably easy to use for simple experiments.
What is Voom Limma?
voom is a function in the limma package that modifies RNA-Seq data for use with limma. Together they allow fast, flexible, and powerful analyses of RNA-Seq data.
How do I know my Bioconductor version?
The best way to check the version of Bioconductor is to compare your version of BiocInstaller (a package within R once Bioconductor is installed) with the Bioconductor website. Mind the . in front of the BioC . That said, it may be possible for some installed packages to have been sourced from a different BioC version.
