# Example:
## Get data from evaluting recipe
recipeLoad('ensembl_liftover', return = TRUE)
ensembl_liftover$species <- 'human'
ensembl_liftover$from <- 'GRCh37'
ensembl_liftover$to <- 'GRCh38'
getData(ensembl_liftover, outdir = 'data/folder', notes = c('grch37', 'grch38'))
## Get data from Google bucket directly
dataUpdate('data/folder', cloud=TRUE)
dh <- dataSearch(c('ensembl', 'GRCh37'))
getCloudData(dh[1], outdir = 'data/folder')
