[BioC] PANTHER in R.... Gene lists in sigPathway?

May be you can get the limma logFC associated values, for associated
GWAS genes, in the example from SPIA, I started only with entrezID's
from KEGG link, and grab the logFC values from limma in sig_genes

sig_genes <- subset(top, adj.P.Val<0.01)$logFC
names(sig_genes) <- subset(top, adj.P.Val<0.01)$ENTREZ

with this code

genes.both <- sig_genes[which(names(sig_genes) %in% genes.via.sel)]

Where  genes.via.sel, was a gene list set of entrezID's to get limma
associated values.

So you can do an approach like this to get associated logFC values
from associated GWAS genes

Also there is another server I known for gene lists


Here you get an analysis combining signaling and metabolic pathways
from Reactome and KEGG databases.

So, R only helps to get the required inputs, for external web appz, or
you can download pantherdb database and write an script for automate
the whole process, from R output

> Hi Felipe,
> Thanks. The thing is that I have genes from both GWAS and DE analysis from Limma in one list. So they don't all have logFC values, hence my question about gene lists and not necessarily gene sets. I ran my list through the PANTHER web interface and got some results but I just wanted to know if it had an R implementation.
