    library(qvalue)
    data(kidney)
    age <- kidney$age
    sex <- kidney$sex
    kidexpr <- kidney$kidexpr
    cov <- data.frame(sex = sex, age = age)

    # create models
    null_model <- ~sex
    full_model <- ~sex + ns(age, df = 4)

    # create deSet object from data
    de_obj <- build_models(data = kidexpr, cov = cov, null.model = null_model,
    full.model = full_model)

    # run the odp method
    de_odp <- odp(de_obj, bs.its = 20)

    # extract out significance results
    qval_obj <- qvalueObj(de_odp)

    # run qvalue and assign it to deSet slot
    pvals <- qval_obj$pvalues
    qval_new <- qvalue(pvals, pfdr = TRUE, fdr.level = 0.1)
    qvalueObj(de_odp) <- qval_new
