GO analysis using clusterProfiler
clusterProfiler supports over-representation test and gene set
enrichment analysis of Gene Ontology. It supports GO annotation from
OrgDb object, GMT file and user’s own data.
support many species
In github version of clusterProfiler, enrichGO and gseGO functions
removed the parameter organism and add another parameter OrgDb, so
that any species that have OrgDb object available can be analyzed in
clusterProfiler. Bioconductor have already provide OrgDb for about
20 species, see
http://bioconductor.org/packages/release/BiocViews.html#___OrgDb, and
users can build OrgDb via AnnotationHub.

enrichGO test the whole GO corpus and enriched result may contains
very general terms. User can use dropGO function to remove specific GO
terms or GO level. If user want to restrict the result at sepcific GO
level, they can use gofilter function. We also provide a simplify
method to reduce redundancy of enriched GO terms, see the
post.

GO analysis using user’s own data
clusterProfiler provides enricher function for hypergeometric test and
GSEA function for gene set enrichment analysis that are designed to
accept user defined annotation. They accept two additional parameters
TERM2GENE and TERM2NAME. As indicated in the parameter names, TERM2GENE
is a data.frame with first column of term ID and second column of
corresponding mapped gene and TERM2NAME is a data.frame with first
column of term ID and second column of corresponding term name.
TERM2NAME is optional.
An example of using enricher and GSEA to analyze DisGeNet annotation is presented in the post, use clusterProfiler as an universal enrichment analysis tool.
GMT files
We provides a function, read.gmt, that can parse GMT file into a
TERM2GENE data.frame that is ready for both enricher and GSEA
functions.
gmtfile <- system.file("extdata", "c5.cc.v5.0.entrez.gmt", package="clusterProfiler")
c5 <- read.gmt(gmtfile)
egmt <- enricher(gene, TERM2GENE=c5)
