I've been trying to annotate probesets of Illumina Human v2 MicroRNA expression beadchip.Its platforms was said to be GPL8179. But I failed to get the annotation db using the code:
library(annotate) affydb<-annPkgName(gset@annotation,type="db") source("https://bioconductor.org/biocLite.R") biocLite(affydb,character.only=TRUE)
bioconductor failed to return a annotation package named GPL8179.db. I wondere if there really exists a annotation package for this miRNA microarray chip. Or should I build one by myself from the start. I really don't know how to do this. I've been stucked here for a long time and hope some kind suggestions.
