## A. SIMPLE EXAMPLE
## ---------------------------------------------------------------------

library(drosophila2probe)
probes <- DNAStringSet(drosophila2probe)

## Check metadata slot: empty
metadata(probes)

## Get generated seqinfo table
seqinfo(probes)

## Subsetting seqinfo table to 10 seqnames
probes10 <- probes[1:10]
seqinfo(probes10) <- seqinfo(probes)[as.character(1:10)]
## See result: 10 seqnames
seqinfo(probes10)
