path <- '/Users/schmidm/Documents/other_people_to_and_from/ClaudiaI/bw'
files <- create_bw_file_set(path, c('rep3', '.bw$'), c('_N20', '_3D12'), c('siRNA', 'ab', 'rep'), '_')
region <- list(chr='chr1', start=1000000, end=1001000, strand='+')
set <- load_bw_set(files, region)
ggplot(set, aes(x=starts, y=scores, color=rep)) + geom_line() + facet_grid(siRNA~ab)
