    motifs <- as.list(matrix.fly)
    motifs <- motifs[grepl("Dmelanogaster-FlyFactorSurvey-", names(motifs), fixed=TRUE)]
    names(motifs) <- gsub("Dmelanogaster_FlyFactorSurvey_", "",
                         gsub("_FBgn[0-9]+$", "",
                              gsub("[^a-zA-Z0-9]","_",

    motifs <- motifs[unique(names(motifs))]
    pfms <- sample(motifs, 10)
    pfms <- lapply(names(pfms), function(.ele, pfms){new("pfm",mat=pfms[[.ele]], name=.ele)},pfms)
    browseMotifs(pfms)
