# A) Ensembl genome:

ensfile <- system.file("extdata",
                        "hs.ensembl.62.small.RData", package="refGenome")
ens <- loadGenome(ensfile)
writeDB(ens, "ens.db3", useBasedir=FALSE)
ens <- loadGenomeDb("ens.db3")

##-------------------------------------##

ucfile <- system.file("extdata", "hs.ucsc.small.RData", package="refGenome")
uc <- loadGenome(ucfile)
writeDB(uc,"uc.db3",useBasedir=FALSE)
uc <- loadGenomeDb("uc.db3")
